α decay to a doubly magic core in the quartetting wave function approach

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