### Abstract

A study of the [Formula Presented]-ray decay of low-lying excited states in fragments produced in the spontaneous fission of [Formula Presented] has revealed a significant correlation between the angles of emission of the [Formula Presented] transitions of complementary fragment pairs. Calculations of the amount of dealignment that is needed to reproduce the measured [Formula Presented] values, and a comparison with the results of previous fragment-[Formula Presented] angular distribution measurements, suggests that at scission there may be significant population of [Formula Presented] substates associated with the projection of the fragment spin vector on the fission axis. Fragments from the spontaneous fission of [Formula Presented] emit [Formula Presented] rays that show markedly reduced interfragment correlations, suggesting that either a larger role is played by the relative angular momentum of the fragments, or that the dealignment introduced by the neutron emission and statistical [Formula Presented] decay to the [Formula Presented] state is larger in [Formula Presented] than [Formula Presented] fission.
