Gamma-gamma angular correlations of transitions in /sup 94/Sr and /sup 96/Sr

Journal Article · · Phys. Rev., C; (United States)
Angular-correlation measurements were made on ten direct cascades and four skip cascades in /sup 94/Sr and on nine direct cascades in /sup 96/Sr. These nuclei were populated by beta decay of isotopically pure /sup 94/Rb and /sup 96/Rb ion beams produced by fission and on-line mass separation. Correlations were measured for most of the intense transitions in coincidence with the 2/sup +/ ..-->.. 0/sup +/ ground-state transition in both nuclei and two additional transitions in /sup 94/Sr. Five levels in /sup 94/Sr are given definite spin assignments and four levels tentative assignments. In /sup 96/Sr definite spin assignments are made for four levels and tentative assignments for five levels. Values are listed for angular-correlation coefficients and, where applicable, multipole mixing ratios. Level systematics of neutron-rich even mass Sr isotopes are discussed within the context of assignments made here.
