Fragmentation dynamics in nuclear fission and in heavy ion collisions

In this article, we have shown that the fragmentation theory based on two centre shell model gives a unified picture of both fission and heavy ion collisions. In the case of fission, the dynamics are shown to occur at a point just past the saddle barrier. Numerical solutions of the stationary and the time dependent Schroedinger equations, in mass or charge asymmetry coordinates, are carried out. Also, models are advanced for the analytical solutions of time dependent Schroedinger equation. The relative motion is treated classically. The theory is illustrated by applying to various phenomena in both fission and heavy ion collisions
