Heavy particle decay studies using different versions of nuclear potentials

Abstract.

The heavy particle decay from ^212-240Pa , ^219-245Np , ^228-246Pu , ^230-249Am , and ^232-252Cm leading to doubly magic ²⁰⁸Pb and its neighboring nuclei have been studied using fourteen versions of nuclear potentials. The study has shown that the barrier penetrability as well as the decay half-lives are found to vary with the nuclear potential used. The investigated decay events of the emission of the clusters ²²Ne , ²⁴Ne , ²⁶Mg , ²⁸Mg , ³²Si and ³³Si are not experimentally detected yet but may be detectable in the future. As most of the half-lives predicted are found to lie within the experimental upper limit, T _1/2 < 10³⁰ s, our predictions will be a guide to future experimental design. The GN plots studied are linear for different cluster emissions from different parents with varying slopes and intercepts. Also, it is to be noted that the linearity of the GN plots is unaltered using different nuclear potentials. The universal curve studied ( log₁₀ T _1/2 vs. -ln P for various clusters emitted from various parents shows a linear behavior with the same slope and intercept irrespective of the nuclear potential used.
