Abstract
The present model describes the exotic decay of nuclei by considering the molecular phase of the fragments in an effective liquid drop description of the process. Shell corrections are included via experimental values of energy released in the disintegration (Q value), which is used to define the effective surface tension of the drop. The Coulomb potential energy is the exact solution of the Poisson equation for a uniform charge distribution in the nuclear volume. The inertial coefficient of the barrier penetrability problem is determined by using the Werner-Wheeler approximation for the velocity field of the nuclear flow. The model is successful in calculating the half-life for both the exotic decay and the α disintegration processes.
