Systematical law of β+-decay half-lives of nuclei far from β-stable line

摘要：

Experimental data of nuclear β+-decay half-lives are systematically analyzed and investigated.We present an exponential law between the half-life of β+-decay with the same forbiddenness and the nucleon number (Z,N) of parent nucleus far from the β-stable line.A formula with four parameters is proposed to describe the β+-decay half-lives of nuclei far from stability.Experimental β+-decay half-lives of the first and second forbidden transitions are well reproduced by this simple formula.The physics of the exponential law is related to the statistical properties of β+-decay far from β-stable line.
