摘要
From an adjustment on a recent selected data set of partial alpha-decay half-lives of 344 ground state to ground state transitions, analytic formulae are proposed depending on the angular momentum of the alpha particle. In particular, an expression allows to reproduce precisely the partial alpha-decay half-lives of even-even heavy nuclei and, then, to predict accurately the partial alpha-decay half-lives of other very heavy elements from the experimental or predicted Q(alpha). Simple expressions are also provided to calculate the potential barrier radius and height.
