The lifetimes of all the known singly excited states in Cu+ and Ag+ were calculated by using a realistic potential (Hartree–Slater) to represent the atomic (ionic) core. Since ab initio calculation of transition wavelengths still lags greatly behind experiment, we used the available experimental values. The results obtained are in good agreement with available sparse experimental data of lifetimes and are intended for guidance of future experimental investigations. The present numerical Coulomb-approximation approach is free from artificial integration cutoffs employed in the various widely used Coulomb approximations.

Theoretical estimates using the CA.
The value 9.68 quoted in Ref. 8 is obviously misprinted since it will yield a lifetime of 0.75 nsec for the 3d95s state, whereas the correct value is around 2.5 nsec.
