Various cluster radioactivities above magic nuclei
Abstract
We present parameter-free tunneling calculations for various cluster radioactivities including the diproton decays of atomic nuclei. An uniform folded cluster potential has been suggested that is based on a self-consistent mean-field model, with the folding factor determined using the quantization conditions of the quasibound cluster state. We have investigated the -particle and heavier-cluster decays of trans-Sn and trans-Pb nuclei, and the observed diproton emission from the proton drip-line nucleus Ne, showing the overall reasonable descriptions of cluster radioactivities with calculated half-lives agreeing well with experimental data. We have also predicted the properties of yet unobserved cluster decays of the exotic nuclei Ba, Te and Ti.
