Determining the probable isotopic existence of superheavy nuclei

Abstract

Superheavy nuclei, due to a higher neutron to proton ratio, its formation is highly complicated and predicting the feasible isotope which can be synthesised is an important task in the research on superheavy nuclei. Here we propose a method for predicting the isotopic feasibility by determining the coexistence of odd-even effect in the context of calculating Eα, T1/2(α) using the binding energy by FRDM model. The prominent decay mode of Superheavy nuclei, α-decay, is been evaluated for Z=101-130 with A= 220-360 by considering both preformed α-cluster and 2n+2p instant decay. The intersection points in the graphs corresponding to the minimum difference between odd and even neutron contribution yield the most probable isotope to be formed and is compared with α-decay half-life calculations by Brown formula. Comparison of the results with known synthesised nuclei yield a close agreement with each other.
