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.
