RADIATIVE LIFETIMES OF THE BOUND EXCITED-STATES OF MAGNESIUM AND BERYLLIUM

We present the radiative lifetimes for series of bound excited states of neutral magnesium and beryllium derived from the transition probabilities calculated in a simple configuration-interaction procedure using a finite basis set constructed from B splines. Our calculated radiative lifetimes compare very well with the most accurate recent state-selected excitation measurements. In particular, our calculation has removed the discrepancy between earlier theoretical and experimental lifetimes for the first few Mg i 3snd 1D states that are strongly affected by the configuration mixing from 3pp configuration series. © 1990 The American Physical Society.
