Energies, wavelengths, and multipole transition probabilities for B-like Fe and Ga ions

Abstract

Energy levels, transition probabilities, oscillator strengths, line strengths, and lifetimes have been calculated for transitions in B-like Fe and Ga ions. The configurations 2s22p, 2s2p2, 2p3, 2s2p3ℓ, and 2p23ℓ were used in the calculations and 125 fine-structure levels were obtained. The fully relativistic GRASP code has been adopted, and results are reported for all electric dipole, electric quadrupole, magnetic dipole, and magnetic quadrupole transitions among the lowest 125 levels of Fe XXII and Ga XXVII, belonging to the n≤3 configurations. Comparisons are made with earlier available theoretical results.
