摘要: Abstract Total and escape widths of IAS in even-A Pm isotopes have been measured via the ANd(3He, t)APm t p )A−1Nd reactions. Values for spreading deduced found to increase strongly with excitation energy through chain isotopes. This behaviour, contrast much smoother global mass number, is attributed a dependence on level density.
