Abstract
We investigate the motion of anα-particle in the average time depencent potentialV(R α ,t) of a fissioning nucleus. The emission process is treated quantum mechanically via a numerical solution of the one-body Schroedinger equation withV(R α ,t). This solution yields the distribution of initial conditions for classical trajectories describing theα-particles outside the Coulomb barrier. The time and shape dependence ofV(R α,t) is shown to have significant influence on the observable angle and energy distribution of theα-particles emitted during fission.
