Radiative parameters for some transitions arising from the 3d94d and 3d84s2 electronic configurations in Cu II spectrum

Abstract

Transition probabilities of 41 transitions originating from the 3d94d and 3d84s2 electronic configurations of singly ionized copper have been determined using laser-induced breakdown spectroscopy. The Cu II ions have been produced by laser ablation. The experimental relative transition probabilities have been converted into an absolute scale using measured branching fractions and theoretical radiative lifetimes of the corresponding upper states obtained by a relativistic Hartree–Fock method taking core-polarization and configuration interaction effects into account. Comparison of the new results with previously available data is also presented.
