Half-Lives and Kinetic Energies for the Spontaneously Emitted Heavy Clusters from Nuclei

摘要

The partial half-lives, branching ratios relative to the alpha decay, kinetic energies and Q-values for the most probable spontaneously emitted heavy ions from 766 nuclides with z=47-106 and total half-lives longer than 1 mu s, are estimated by using the analytical supersymmetric fission model, a semiempirical formula for alpha -decay life-times which are not measured, and the Wapstra-Audi new mass tables. Even the so-called 'stable' nuclides with Z > 40 are meta-stable relative to the new decay modes. The experimental evidences are briefly reviewed. (ERA citation 11:018613)
