$\alpha$-Decay Lifetime in Superheavy Nuclei With $A>282$

Abstract

Nuclei with $A>282$ have been studied in the Relativistic Mean Field approach using the force FSU Gold and a zero range pairing interaction. The Euler-Lagrange equations have been solved in the co-ordinate space. Alpha nucleus potential has been constructed with the DDM3Y1 interaction, which has an exponential density dependence, in the double folding model using the nucleon densities in the daughter nucleus and the $\alpha$ particle. Half lives of $\alpha$ decay have been calculated for tunneling of the $\alpha$ particle through the potential barrier in the WKB approximation and assuming a constant preformation probability. The resulting values agree well with experimental measurements.
