Laboratory work «Study of multiphoton ionization under conditions of resonant excitation of atomic vapors»

I. G. Kirin

The developed laboratory work is described, designed to study multiphoton ionization under conditions of resonant excitation of atomic vapors by frequency-tunable laser radiation. Atomic pairs of potassium and rubidium were chosen as objects of study. To demonstrate the resonant nature of multiphoton ionization, the results of studies of the dependence of the magnitude of the ion signal on the frequency of laser radiation causing this signal are presented. Analytical expressions are given to describe the experimentally observed patterns of resonant ionization processes. Laboratory work is part of a set of works on the study of resonant nonlinear optics for students studying physics at universities.The developed laboratory work is described, designed to study multiphoton ionization under conditions of resonant excitation of atomic vapors by frequency-tunable laser radiation.

Collisional and thermal ionization of sodium Rydberg atoms: I. Experiment fornS andnD atoms withn= 8–20

I. I. Ryabtsev, Denis B. Tretyakov, Ilya I. Beterov +3 more

Collisional and thermal ionization of sodium n S and n D Rydberg atoms with n = 8–20 has been studied. The experiments were performed using a two-step pulsed laser excitation in an effusive atomic beam at atom density of about 2 × 10 10 cm −3 . Molecular and atomic ions from associative, Penning and thermal ionization processes were detected. It was found that the atomic ions were created mainly due to photoionization of Rydberg atoms by photons of blackbody radiation at the ambient temperature of 300 K. Blackbody ionization rates and effective lifetimes of Rydberg states of interest were determined. The molecular ions were found to be from associative ionization in Na( nL ) + Na(3S) collisions. Rate constants of associative ionization have been measured using an original method based on relative measurements of Na + 2 and Na + ion signals.Collisional and thermal ionization of sodium n S and n D Rydberg atoms with n = 8–20 has been studied.

Rydberg Atoms: From Determinism to Chaos

Nikolai N. Bezuglov, Gennady V. Golubkov, Andrey N. Klyucharev

R.F. Stebbings and F.B. Dunning were the editors of Rydberg States of Atoms and Molecules . Issued in 1983, this book actually reflected the emergence of a new field in atomic and molecular physics, which subsequently resulted in a number of applications in academic sciences and technology. In this paper, we analyze the results obtained in recent years for ionization processes in collisions of heavy particles with the participation of Rydberg atoms in a wide energy range. These results have been actively used in modern applications of atomic physics. In addition, we consider the influence of nonlinear resonant interaction of Rydberg complexes with electromagnetic waves on the rate of propagation of satellite signals in the atmosphere.R.F.
