Description |
The Q-values and half-lives of several heavy alpha decaying systems are calculated using the relativistic mean field (RMF) theory-based microscopic alpha-daughter nucleus potential. A unified procedure is adopted, using analytic S-matrix method and treating alpha-decay as the decay of the resonance state of the alpha-daughter nucleus system. The resonance parameters are obtained from the pole positions of the S-matrix in the complex k-plane and using these Q-values and half widths are evaluated. The calculation reproduces the experimental results well. We find that the present unified approach gives a good description of the data and compare well with those obtained by empirical formulae.
