We discuss the old problem of atom stability and atomic spontaneous emission, which was studied from Einstein introducing the idea of photon which was exploited by Bohr for its subsequent atomic model and its postulate of atomic quantum jumps.We expose then briefly the first historical model of unstable particles elaborated from Gamow which was based on the hypothesis of a constant lifetime describing the decaying process of unstable particles; we discuss then the relevance of this topic for our critique to the existence of hypothetical individual stationary atomic states.We propose a dynamic deterministic alternative approach to quantum unstable states and we suggest a possible alternative justification of Bohr formula of quantized energy spectra of the hydrogen atom.We assume that each atom is an open state that it is continuously radiating and interacting with the other accelerated atoms and that the stationary atomic spectra are an emergent effect caused by the equilibrium with the real electromagnetic pilot wave.We suggest consequently that the hydrogen gas is, with respect to each atom, an effective space time dependent polarized medium with a hidden variable light speed.We generalize the classical formula of spontaneous emission of Einstein and that one of Gamow substituting the standard light speed with a space dependent one.Finally we attempt to extend this approach to every atomic states and we propose a dynamical model of stationary quantum states that could allow to explain atomic stability and deduce dynamically the Bohr formula.

We discuss the problem of the generalization of Bell local hidden variable models for unstable particles as nucleons or decaying quantum bound states. We propose to extend the formalism of real deterministic hidden variables in the complex domain, in analogy with the quantum Gamow ket formalism, and we introduce a time dependent classical probability density distribution by which we implement hidden time dependence in the quantum expectation values. We suggest therefore a classical framework which may recover by asymptotic temporal limits the standard Bell stationary quantum statistical averages. Endly we discuss the possible relevance of our proposal for general non-isolated quantum systems in noninertial frames and the consequent dynamic effects of vacuum instabilities on E.P.R tests and Q.M. ensemble statistical averages.

The atom model of Niels Bohr is commonly considered as antiquated even if it describes the atomic spectrum of hydrogen quite accurately. The later published relation of Louis De Broglie could arithmetically be implemented into Bohr’s formulation, leading to the concept of standing waves as the existence cause of excited electron states. However, at that time it was not possible to find well defined electron trajectories being classically describable. As a consequence, the »quantum mechanics« were developed by several authors, particularly by Schrodinger and by Heisenberg, but delivering a hardly under¬standable formalism where the classical physical laws appear being abrogated while abstract terms replace concrete and imaginable ones, abandoning the particle perception of mass points. In particular, Heisenberg’s »uncertainty principle« and the assumption of state probabilities seem to be in a striking variance to the idea of standing waves. In contrast, a formulation is given here which exactly describes the electron trajectories in the exited states solely by applying classical physical laws. Firstly, the original Bohr-model - in combination with De Broglie’s relation - is rolled up. From this formula system a vibration frequency - corresponding to the De-Broglie frequency – is deduced which is n-times larger than the rotation frequency of the Bohr-model. Furthermore, a direct coherence between that vibration-frequency of the electron and the frequency of the involved light is evident being explainable as a resonance effect. Then, a three-dimensional model is proposed where the electron oscillates and pulses perpendicularly to a virtual rotation plane i.e. rotating around a vertical axis, accompanied by a perpetual energy exchange between potential and kinetic energy. This leads at the excited, metastable energy states to well-defined, three-dimensional and wavy trajectories winding up on a surface similar to the one of a hyperboloid, whereas at the ground state the trajectory is planar and stable.
Introduction The preceding chapters have focused on atomic transitions induced by applied radiation. That is, there is an optical field illuminating the atoms, and their response is calculated. It is implicitly assumed that an excited atom left alone will spontaneously return to the ground state, and conserve energy by emitting light that satisfies E 2 − E 1 = ħ ω 21 in accordance with the Planck and Bohr pictures. But this spontaneous emission process is not addressed quantitatively in these earlier chapters. Spontaneous emission is one of the most pervasive phenomena of atomic physics, and yet its origins remain among the least well-understood. The number of misconceptions is enormous, and they are to be found in textbooks, journal articles, and lecture notes. Because the natural decay of an excited atom adds energy to what is usually an empty mode of the electromagnetic field, the process is fundamentally quantum mechanical. Classical or even semi-classical descriptions cannot be assured to give correct answers. This is not to say that such discussion is to be avoided, but only that caution is needed in interpreting the results. Toward the end of the nineteenth century, many experimental results made it clear that classical mechanics needed to be supplemented by new theories. The first venture into the new physics was Planck's hypothesis that the energy of classical radiating oscillators like those discussed in Chap. 1 would have to be quantized into integer multiples of ħ ω. This notion led to his famous formula for the spectrum of thermal radiation from a non-reflective object (black body), and this formula describes a radiation field in thermodynamic equilibrium with its environment. The result of Planck's hypothesis in the context of thermal equilibrium plays a vital role in the discussion of spontaneous emission. Einstein A - and B -coefficients Soon after Bohr proposed a model of atomic structure consisting of discrete energy levels, connected by radiation whose energy satisfied Δ E = ħω when atoms made transition between them, Einstein published the first serious attempt to connect the absorption and emission processes. Absorption, he reasoned, could occur only in the presence of applied radiation, whereas spontaneous decay occurred without the application of any field.
The spontaneous decay of an excited atom by photon emission is one of the most common and elementary physical process present in nature and in laboratories. The decay is random in time with constant probability density, as it can be inferred by the exponential law observed experimentally. Despite the simplicity of the process, in Quantum Mechanics the decay itself is considered a law of nature which is not further analyzed or explained. However it is legitimate to ask for the reason of its randomness and for the dynamics of the atom around the decay. The decay process of an isolated atom is usually assumed to be instantaneous, the so called Quantum jumps. Particular experimental arrangements can widen the duration of the transition from an excited state to the ground state to a finite time. In general this is due to the quantum back action of the detector. The development of Quantum Optics has enormously enriched the possibilities to study in detail the process, and new illuminating insights have been obtained, but the question is still valid and its answer is still elusive. In this paper we analyze the spontaneous decay within the new prospect introduced by a recent model that complete standard Quantum Mechanics in a formalism which is able to describe the dynamics of measurement and of spontaneous decay. Comparison is made with more phenomenological theories, the Quantum Mechanics of open system and the Stochastic wave function model. In the new model the stochastic photon emission by an excited atom is triggered by the vacuum fluctuations. It is suggested how to re-analyze three types of experiments, already realized in many laboratories, in order to reveal the presence and the effect of these fluctuations.
The historical development of atomic theory proceeded through a sequence of increasinglysuccessful mathematical descriptions of atomic behavior. The Bohr model introducedquantized electron states but retained classical orbital motion, creating a conflict withMaxwellian electrodynamics. Quantum mechanics subsequently abandoned the conceptof observable electron orbits and replaced deterministic trajectories with probabilisticwavefunctions and observable operators. While extraordinarily successful in prediction,the standard framework remains largely silent regarding the physical mechanismunderlying quantization, wavefunction collapse, and the transition between localizedparticles and distributed waves.Space-Phase Theory (SP3) proposes that a physical medium exists throughout space andthat matter, energy, and fields arise from organized states of that medium. Within thisframework, the atom is interpreted as a stable nested organization of space-phasestructures rather than as particles moving through empty space. Electrons are treated aslocalized saturation states of the medium, photons as propagating organized disturbances,and atomic energy levels as stable coherence configurations supported by the mediumitself.This paper develops an SP3 interpretation of atomic structure, demonstrates how atomicstability emerges naturally from medium dynamics, examines photon emission andabsorption as medium reconfiguration processes, and explores how atomic organizationmirrors larger-scale structures throughout nature. The resulting model offers a mechanismbased interpretation of quantization while preserving the observational successes ofmodern quantum theory
