A number of fission products possess isomeric states which have a nuclear spin significantly different from that of the ground state. The yield ratio of these states following fission is influenced by the angular momentum present in the fissioning system. The 134m,134Sb yield ratio had not been previously measured in the spontaneous fission of 252Cf; however, it had previously been observed to favor the (7−) isomer over the (0−) ground state in 235 U (nth,f) and 232 Th (25 MeV p,f).
