Nuclear $\gamma$ Rays Following $K^{-}$ Capture

It is suggested that the study of the nuclear deexcitation $\gamma$ rays emitted following $K^{-}$ capture may help clarify the nature of the capture mechanism. We consider capture in ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ and ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$. Capture rates to the various proton or neutron single-hole states in ${}_{}{}^{207}{}_{}{}^{}\mathrm{Pb}$, ${}_{}{}^{207}{}_{}{}^{}\mathrm{Tl}$, ${}_{}{}^{15}{}_{}{}^{}\mathrm{O}$, and ${}_{}{}^{15}{}_{}{}^{}\mathrm{N}$ are estimated, and the consequences of capture to the isomeric states in ${}_{}{}^{207}{}_{}{}^{}\mathrm{Pb}$ and ${}_{}{}^{207}{}_{}{}^{}\mathrm{Tl}$ are discussed.
