Neutron-deficient N≈126 Nuclei Produced in 238U Fragmentation: Population of High-spin States

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding

Abstract

The population of metastable states produced in relativistic-energy fragmentation of a 238U beam has been measured. For states with high angular momentum, I=17 and I=21.5, a higher population than expected has been observed, with the discrepancy increasing with angular momentum. By considering two sources for the angular momentum, related to single-particle and collective motions, a much improved description of the experimental results can be obtained. In addition, new results on the structure of 208Fr, 211Ra and 216Ac are reported.
