Abstract: Abstract: We have applied the second-order relativistic many-body perturbation theory to calculate the oscillator strengths for the spin-allowed electric-dipole (E1) transitions in Zn I and Ga II. We have studied 11 transitions among the first 12 levels of Zn I and Ga II. Radiative lifetimes of some levels in Zn I and Ga II are also evaluated. In particular, the present study provides the first relativistic calculation for the transitions $(4{\rm s}4{\rm p})\ ^{3}{\rm P}_{0,1,2}^{o}\rightarrow (4{\rm p}^{2})\ ^{3}{\rm P}_{0,1,2}$ in Zn I whose oscillator strengths are sensitive to the interplay between the relativistic effects and the bound–continuum correlations. The transition amplitudes obtained in different gauges agree within 2%. The present results agree well with experiment.
