Comparative study of the alpha decay of Hg isotopes using different forms of nuclear potentials

摘要

The alpha decay half-lives of Hg isotopes within the range A = 171–212 have been studied using 25 different versions of nuclear potentials to select the suitable form of nuclear potential for alpha decay studies. The computed standard deviations suggested that the apt potential is BW 91 with a deviation 0.133. The next low deviation is shown by Proximity 1966, Proximity 1984, and Proximity 2003-I, II with deviations less than 0.2. Concerning other potentials, the fact we observed is that almost all the potentials possess a standard deviation less than one. The universal curve studied for alpha decay is observed to show straight line behavior irrespective of the nuclear potential used. Since the predicted alpha half-lives match well the experimental values, the half-lives of certain new Hg alpha emitters have been predicted by the present method.
