Relativistic mean field study of the newly discovered $\alpha$-decay chain of ${}^{287}$115

Abstract

The single particle structure of the low lying levels in the nuclei belonging to the newly observed $\alpha$-decay chain starting from ${}^{287}$115 has been studied. Relativistic mean field calculation with two forces NL1 and NL3 has been performed in the blocked BCS approximation. Q-values for possible decay have been calculated and compared with experiment. Lifetime estimates obtained from phenomenological relations have also been compared.
