Evidence for sudden of rotational structure in heavy Sr nuclides

The authors give evidence for rotational 2/sup +/ and 4/sup +/ levels in /sup 100/Sr. The nuclide /sub 37//sup 100/Rb with half-life of 55 ms was produced by mass separation at the ISOLDE Facility by bombarding a uranium carbide target with 600 MeV protons. The gamma- ray spectrum shows peaks that t...

Sumario:The authors give evidence for rotational 2/sup +/ and 4/sup +/ levels in /sup 100/Sr. The nuclide /sub 37//sup 100/Rb with half-life of 55 ms was produced by mass separation at the ISOLDE Facility by bombarding a uranium carbide target with 600 MeV protons. The gamma- ray spectrum shows peaks that the authors interpret from systematics as the 4/sup +/ to 2/sup +/ and 2/sup +/ to 0/sup +/ gamma-ray transitions in strontium. Similar measurements on /sup 98/Rb confirm earlier findings by Wollnick et al. (1977). The level diagrams clearly show an abrupt onset of deformation at N=60. (4 refs).
