摘要：
Conversion electrons from the decay of a spin isomer in the secondary minimum of Pu239 have been measured. They are interpreted as transitions feeding and depopulating a rotational band built on the fission isomeric ground state with spin 52. Rotational parameters of A=3.36±0.10 keV and B=4±3 eV have been deduced. The observed upper limit on the M1E2 mixing ratio of 1.4 suggests an antiparallel coupling between orbital angular momentum and spin vectors for the wave function of the fission isomer. © 1979 The American Physical Society.
