Liquid drop surface dynamics for large nuclear deformations

Abstract

Macroscopic dynamical equations for the effective nuclear surface in terms of the collective variables are derived within the framework of the liquid drop model for large deformations. The inertia and friction parameters are calculated for Lorentz parametrization of nuclear shape in the case of incompressible and irrotational flow. We found the noticeable discrepancy between our results for the calculated friction tensor components related to the ‘‘neck’’ degree of freedom and obtained in other macroscopic models.
