Alpha decay half-lives of odd-Z superheavy elements Z = 115→113→111

Abstract

We present theoretical calculations on α-decay half-lives of the heaviest odd-Z elements 115→113→111 by the density-dependent cluster model. The microscopic potential between the α-particle and the daughter nucleus is evaluated numerically from the double-folding model with the standard M3Y nucleon-nucleon interaction. The calculated α-decay half-lives with renewed Qα values are systematically compared with the experimental data.
