Abstract

A comprehensive compilation and evaluation of beta-delayed neutron (β−n) emission probabilities, Pn, and associated half-lives for A ≤ 72 nuclei has been performed for the first time. The recommended values have been used to analyze the systematics of β−n emission in this region. The ratio Pn/T1/2 is better correlated with the Q-value of the β−n decay mode than the previously proposed Kratz-Herrmann Formula (KHF). The recommended values are also compared with theoretical quasi-particle random phase approximation (QRPA) calculations.
