Fission fragment isomers populated viaLi6+Th232

Short-lived isomers in fission fragments following bombardment of 45-MeV $^{6}\mathrm{Li}$ on $^{232}\mathrm{Th}$ were examined. Isomers in the $A~95,122,$ and 132 mass regions were observed. New isomeric decays were observed in $^{121}\mathrm{In}$ [${T}_{1/2}=17(2) \ensuremath{\mu}$s], $^{123}\mathrm{In}$ (${T}_{1/2}\ensuremath{\gtrsim}100 \ensuremath{\mu}$s), and $^{125}\mathrm{Sb}$ [${T}_{1/2}=25(4) \ensuremath{\mu}$s]. These isomers are suggested to arise from $\ensuremath{\nu}({h}_{11/2}\ensuremath{\bigotimes}{d}_{3/2}){7}^{\ensuremath{-}}$ and $\ensuremath{\nu}({h}_{11/2}\ensuremath{\bigotimes}{s}_{1/2}){5}^{\ensuremath{-}}$ neutron core excitations coupling with the valence proton.
