The Rotation of Scissioning Nucleus Considered Trajectory Calculations for Ternary Fission Induced by Cold Polarized Neutrons

摘要

On the base of modified trajectory calculations the shift of angular distribution of a-particles accompanied the reaction ~(235)U(n, f) induced by cold polarized neutrons is evaluated. It was supposed that angular distribution shift is caused by the rotation of nuclear system before scission. The orientation of a rotation motion is determined by the neutron spin polarization along and opposite to the beam direction. For the first time the estimation was done in the frame of trajectory calculations assuming the rotation motion of scissioning nucleus [1]. The result of the calculation is in a good agreement with experimental data of paper [2], where this new phenomenon was named as ROT-effect.
