摘要: Abstract Using an on-line mass spectrometer the delayed neutron emission probability P n and half-lives of new precursors 97 Rb, 98 145 Cs 146 have been measured. The values known 93–96 Rb were remeasured upper limit was found for β-delayed double-neutron Rb. experimental 92–98 are discussed within a simple semi-empirical picture.
