Neutron Shell Closure

The alpha-decay half-lives of the 24 isotopes of Eu (Z = 63) nuclei in the region 130≤A≤153, have been studied systematically within the Coulomb and proximity potential model (CPPM). We have modified the assault frequency and re-determined the half-lives and they show a better agreement with the experimental value. We have also done calculations on the half-lives within the recently proposed Coulomb and proximity potential model for deformed nuclei (CPPMDN). The computed half-lives are compared with the experimental data and they are in good agreement. Using our model, we could also demonstrate the influence of the neutron shell closure at N = 82, in both parent and daughter nuclei, on the alpha-decay half-lives.

Dependent Potential

The half-lives of deformed nuclei are reported. We consider an angle-dependent potential which yields multipole approximations. We see that the results are in better agreement with the experimental data when the multipole approximation is solely considered for the daughter nuclei.

First Time

A systematic study on the alpha decay half-lives of various isotopes of superheavy element (SHE) [Formula: see text] within the range [Formula: see text] is presented for the first time using Coulomb and proximity potential model for deformed nuclei (CPPMDN). The calculated [Formula: see text] decay half-lives of the isotopes within our formalism match well with the values computed using Viola–Seaborg systematic, Universal curve of Poenaru et al., and the analytical formula of Royer. In our study by comparing the [Formula: see text] decay half-lives with the spontaneous fission half-lives, we have predicted [Formula: see text] chain from [Formula: see text]121, [Formula: see text] chain from [Formula: see text]121 and [Formula: see text] chain from [Formula: see text]121. Clearly our study shows that the isotopes of SHE [Formula: see text] within the mass range [Formula: see text] will survive fission and can be synthesized and detected in the laboratory via alpha decay. We hope that our predictions will provide a new guide to future experiments.
