PATH-INTEGRAL APPROACH TO NO-CORIOLIS APPROXIMATION IN HEAVY-ION COLLISIONS

We use the two time influence functional method of the path integral a pproach in order to reduce the dimension of the coupled-channels equat ions for heavy-ion reactions based on the no-Coriolis approximation. O ur method is superior to other methods in that it easily enables us to study the cases where the initial spin of the colliding particle is n ot zero. It can also be easily applied to the cases where the internal degrees of freedom are not necessarily collective coordinates. We als o clarify the underlying assumptions in our approach.
