ANALYSIS OF 3-PRONG EVENTS IN THE HEAVY-ION INTERACTION OF 17.0 MEV UXE-132+U-238/

The heavy ion nuclear interaction Xe-132 + U-238 has been investigated at the beam energy of 17.0 MeV/u, employing the 2 pi-geometry techniq ue and using mica as a Solid State Nuclear Track Detector (SSNTD). Aft er measuring the spherical polar coordinates of the correlated tracks, event-by-event, the three-prong events have been analysed numerically using an empirical range-mass-energy relationship. The coefficients o f this relationship were deduced from the experimental data of the ela stic events as well as three-prong events in a self-consistent manner. The intermediate stage of the reaction has been constructed from the knowledge of the relative velocities of the fragments observed in the final stage of the reaction and hence mass transfer between projectile and target has been determined. The emission of final fission fragmen ts were examined in both in-plane and out-of-plane of the reaction.
