Abstract

Short-lived isomers in fission fragments following bombardment of 45-MeV ⁶Li on ²³²Th were examined. Isomers in the A ~ 95,122, and 132 mass regions were observed. New isomeric decays were observed in ¹²¹In [T_1/2=17(2) μs], ¹²³In (T_1/2≳100 μs), and ¹²⁵Sb [T_1/2=25(4) μs]. These isomers are suggested to arise from ν(h_11/2⊗d_3/2)7⁻and ν(h_11/2⊗s_1/2)5⁻ neutron core excitations coupling with the valence proton.
