Rydberg atoms in parallel magnetic and electric fields. I. Experimental studies of the odd diamagnetic multiplet of lithium: n mixing and core effects

Patrice Cacciani, Sylvain Liberman, Eliane Luc-Koenig +2 more

A quasihydrogenic complete diamagnetic manifold is investigated experimentally. The spectra are obtained in a uniform magnetic field by exciting in a one-step process, using polarised laser light, the lithium atoms of an atomic beam. The whole structure of the M=0 odd diamagnetic multiplet has been recorded for the first time. This experiment provides a confirmation for the existence of the two classes of states predicted for the diamagnetic Hamiltonian of atomic hydrogen in the weak-field limit. The fundamental features of diamagnetism still subsist for such high field strengths so that the diamagnetic interaction cannot be regarded as a perturbation with respect to the Coulomb problem. The intermanifold coupling and the influence of effects due to the ionic core in the lithium atom are evaluated quantitatively.

Numerical study of Rydberg Cs atoms in parallel electric and magnetic fields

Wenyu Liu, Baiwen Li

Using a potential model method, we calculate the Stark evolution of the diamagnetic manifolds of Rydberg caesium. Results show that general features appearing in hydrogen lithium and helium are found in caesium. But significant modifications characteristic of atomic species and magnetic field strength are also evident and are attributed to core effects. We also find numerical manifestations of the fine structure effect of Rydberg states in strong external fields which have been long neglected.

For pt. I see ibid., vol.21, no.21, p.3473-98 (1988). The semiclassical approach based on the secular perturbation method, primarily introduced by Solov'ev (1982) to study the pure diamagnetism of hydrogen in the weak-field limit, is extended to the case where the atom is subjected to electric and magnetic fields both parallel to the 0z direction. The structure of the manifold of states with principal quantum number n is governed by the existence of an approximate constant of motion and the states can be classified into three groups. The semiclassical Bohr-Sommerfeld quantisation rule allows the energy of the states to be calculated. The main properties of the spectra and their evolution when one of the fields increases are analysed. An original comparison between the structure of the pure diamagnetic n multiplet with azimuthal quantum number M not=0 and the structure of the n, M=0 multiplet with parallel fields is proposed.
