Strutinsky - Denisov polarization in fission fragments

The hard electric dipole radiation from fission fragments of 235U by thermal neutrons is predicted. The radiation arises due to the Strutinsky - Denisov induced polarisation mechanism. The probability of the radiation is at the level of 0.0025 per fission, which is in agreement with experiment. The angular distribution exhibits left-right asymmetry with respect to the plane perpendicular to the neutron polarisation axis. That means that the emission of a gamma quanta at the given angle depends on the neutron polarisation. The asymmetry is at the level of 10-3. This effect is similar to that observed earlier for gamma quanta in binary- and alphas - in ternary fission.
