EFFECTIVE INERTIAL COEFFICIENT FOR THE DINUCLEAR REGIME OF THE EXOTICDECAY OF NUCLEI

Geometric and incompressibility constraint relations are used explicit ly in reducing the number of collective variables of the dinuclear pha se of the fissioning system to calculate the barrier penetrability fac tor. Consistently, we define an effective inertial coefficient for the relative motion of the fissioning system. With this inertial coeffici ent, half-lives of the exotic and alpha decays are successfully reprod uced for all available experimental data, using only one well-controll ed nuclear parameter, the nuclear radius constant.
