Abstract

This microscopic calculation for the $\ensuremath{\alpha}$ decay of heavy nuclei provides a solution to what has long been an outstanding problem. In the authors' model, the $\ensuremath{\alpha}$ particle exists only below about one-fifth of saturation density, corresponding to a large radius, inside of which the $\ensuremath{\alpha}$ particle transitions into an unbound four-nucleon shell-model state. The model reproduces the half-life of ${}^{212}$Po (a classic test case) as well as some neighboring nuclei, and calculations are also made for ${}^{104}$Te.
