Electron capture of ${}^{123}\mathrm{Te}$ from the K shell has been investigated in a new underground search with an array of 340-g ${\mathrm{TeO}}_{2}$ thermal detectors. We find that some previous indication of this decay could be attributed to electron capture (EC) of ${}^{121}\mathrm{Te}$ resulting from neutron activation of natural tellurium. There is therefore so far no evidence for EC of ${}^{123}\mathrm{Te}$ from the K shell with a 90% C.L. lower limit ${t}_{1/2}^{K}g5\ifmmode\times… Expand
