After a comprehensive compilation and evaluation of beta-delayed neutron (β^-n) emission probabilities, P_n, 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^-nemission in this region. The ratio P_n/T_1/2 is better correlated with the Q-value of the β^-n decay mode than the previously proposed Kratz-Herrmann Formula (KHF). Moreover, the recommended values are also compared with theoretical quasi-particle random phase approximation (QRPA) calculations.
