Abstract

Radiative lifetimes of some of the levels in the Cu II 3<i>d</i><sup>9</sup>4<i>p</i> and 3<i>d</i><sup>9</sup>5<i>s</i> configurations have been measured to accuracies of 10–20% by using a delayed-coincidence technique. Relative line strengths for the 3<i>d</i><sup>9</sup>4<i>s</i>-3<i>d</i><sup>9</sup>4<i>p</i> and 3<i>d</i><sup>9</sup>4<i>p</i>-3<i>d</i><sup>9</sup>5<i>s</i> arrays have been determined both theoretically and experimentally. The theoretical line strengths are based on intermediate-coupling calculations, and the experimental ones are based on branching-ratio measurements and the J-file sum rule. Good agreement between the two sets of values is obtained; agreement is more satisfactory for the 4<i>s</i>-4<i>p</i> array than for the 4<i>p</i>-5<i>s</i> array. The experimental line strengths are estimated to be accurate to 10% for the 4<i>s</i>-4<i>p</i> array and to 30% for the 4<i>p</i>-5<i>s</i> array. Transition probabilities are determined by normalizing the experimental line strengths to an absolute scale by using the measured lifetimes.
