Abstract

We have investigated the $K$ -shell electron-capture decay of ${}^{158}{Tb}$ , and, contrary to an earlier claim, we find no evidence for $K$ capture to a state at 1187 keV. Our results are consistent with recent measurements of related reaction $Q$ values and invalidate the claim that ${}^{158}{Tb}$ decay is useful for determining the mass of the neutrino.
