Transition probabilities of some Ag II and Cu II lines

摘要

Experimental transition probabilities arising from 4d~8 5s~2, 4d~9 6s and 4d~9 5d levels of Ag II and 3d~8 4s~2 level of Cu II were measured. A time-resolved system with a Nd-YAG laser that produced free neutral and ionised silver and copper plasma by ablation was used. Transition probabilities were deduced by measured branching ratio and experimental and theoretical data for radiative lifetimes. A comparision between our values and the theoretical ones is made where available.
