Abstract

We report on beam-foil time-of-flight measurements of forbidden transitions in H-like and He-like Nb and Ag. The lifetimes of the 2 ${}^{1}$ $S_{0}$ state of He-like Nb, the 2 $s_{1 / 2}$ state of H-like Ag, and the 2 ${}^{3}$ $P_{2}$ state of He-like Ag have been measured with precisions ranging from 1.7% to 10%. These are the highest-Z ions for which these lifetimes have been measured.
