- Description
- Half-life values of spontaneous nuclear decay processes are presented in the framework of the Effective Liquid Drop Model (ELDM) using the combination of varying mass asymmetry shape description for the mass transfer with Werner-Wheeler's inertia coefficient {\sc Vmas}/WW. The calculated half-lives of ground-state to ground-state transitions for the proton emission, alpha decay, cluster radioactivity, and cold fission processes are compared with experimental data. Results have shown that the ELDM is a very efficient model to describe these different decay processes in a same, unified theoretical framework. A Table listing the predicted half -life values, $\tau _{\text{{\rm c}}}$, is presented for all possible cases of spontaneous nuclear break-up such that $-7.30\lesssim \log _{10}\tau _{\text{{\rm c}}}$ [s] $\lesssim 27.50$ and $\log _{10}(\tau /\tau _{\text{{\rm c}}})>-17.0$, where $\tau $ is the total half-life of the parent nucleus.
