Improving systematic predictions of β-delayed neutron emission probabilities

RADIOACTIVITY Z=2-57(β^-n); analyzed correlation between β-delayed neutron emission probabilities %β^-n and corresponding half-lives from experimental data. Comparisons with KHF systematics for fission-region nuclei, and with Moller's QRPA calculations. Proposed improved systematics for prediction of %β^-n values.
