Radiative Lifetimes of Rydberg States in Neutral Gallium

Abstract

Radiative lifetimes were calculated using weakest bound electron potential model theory for 4s 2 ns5/2 (n ≥ 6) series in neutral gallium. The use of the quantum defect theory and Martin's expressions allowed us to supply lifetime values along by means of the series above. The results obtained in this work presented good agreement with theoretical and experimental values. Moreover, some lifetime values not existing in the literature for highly excited Rydberg states in gallium atom were obtained using this method.

Transition Probabilities, Oscillator Strengths and Line Strengths Result From Radiative Transitions

“…This idea and quantum defect models were recently combined by Zheng et al in the weakest bound electron potential model theory (WBEPM). The foundation of WBEPM rests on the proposal that in any system, the orbiting electrons may be grouped into the weakest and the non-weakest bound electrons [12][13][14][15][16]. The weakest bound electron is supposed to be in a field created by the nucleus and inner core electrons.…”

“…Therefore, the two s electrons form a closed sub-shell, the residual electron gives rise to an alkali-like spectrum [912]. The most of investigations in literature are limited few low excitations radiative lifetimes (n ≤ 812) [13].…”
