摘要

Abstract

Recently, we analyze the ,α,-decay data of even-,Z, nuclei and propose the new Geiger-Nuttall law where the effects of the quantum numbers of ,α,-core relative motion are naturally embedded in the law [Physical Review C 85, 044608 (2012)].In this paper, we firstly test whether the new law without any change of parameters can be applied to the,α,-decays of odd-,Z, nuclei which are more complicated than those of even-even nuclei. Then the nuclear shell effect around ,N,=126 is analyzed for very proton-rich nuclei with ,Z,=85–92 based on the data of ,α,-decay energies and half-lives. A long-lived island beyond the stable line is proposed where the half-lives of nuclei on this island are abnormally long. The mechanism of the appearance of the island and its significance to other mass ranges are discussed.
