Decay of 10.4-minGd162

Abstract

A short-lived ${\mathrm{Gd}}^{162}$ isotope has been produced by double neutron capture during the Savannah River high-flux reactor experiment. The new isotope decays with a half-life of 10.4\ifmmode\pm\else\textpm\fi{}0.2 min to the 7.4-min isomer of ${\mathrm{Tb}}^{162}$. Gamma rays of 410 and 428 keV were observed in the decay of 10.4-min ${\mathrm{Gd}}^{162}$.
