摘要: Abstract The neutron spectrum following the beta-decay of 9Li is studied with a time-of-flight spectrometer. A group 0.68 MeV seen corresponding to decay ground state 8Be 2.43 9Be; energy 1.2±0.1 and width 1.0±0.2 corresponds level in 9Be at 3.0±0.1 MeV. It suggested that this “missing” J π = 1 2 − predicted by independent particle model. log ƒt value (5.2±0.2) for β-decay its absolute agree expectation 9Be(e,e′)9Be data are consistent such provide measure M1 radiative adequate agreement
