The sodium D2-line in electric and magnetic fields

Abstract

Abstract. The influence of perpendicularly crossed electric and magnetic fields of comparable strength on the hyperfine components of the sodium Dz-line was studied by means of laser-atomic-beam spectroscopy. The observed spectra show changes in the polarization type (a, re) when one of the fields becomes dominant relative to the other. Theoretical calculations confirm the experimental observations.

The sodium D2-line in electric and magnetic fields. Part III: adiabatic hyperfine level transfer in perpendicularly crossed fields

“…2 Although the spectra obtained in [5] confirm that the computed energy splittings considered here are correct, a direct confirmation of the level transfer would reinforce the model adopted here. Following the suggestion presented in [ 1 ] an experiment is under way in order to show if a population transfer from one hyperfine level to another one can be directly observed.…”

Tensor polarizability of cadmium atoms in the excited state (5s5p)3 P 1

“…In several laboratories systematic measurements of atomic polarizabilities are carried out for different species and from some others theoretical results were reported of calculations of static as well as dynamic polarizabilities. Recently several papers were punished reporting experimental results of scalar and tensor polarizabilities of helium [2], tensor polarizabilities of the Sc, Y, La and Lu [3], of neutral rare-earth atoms [4] and the influence of electric and magnetic fields on sodium atoms [5]. In this paper, we present the measurements of polarizability of cadmium atoms in electric field using the level crossing and the opto-magnetic double resonance methods in combined electric and magnetic fields.…”
