摘要
An excited rotational band including seven new gamma transitions was identified in Sr-97 from gamma-gamma-gamma coincidences in the spontaneous fission of Cf-252. This new band, built on the 829.8-keV state, is interpreted as the nu9/2[404] rotational band with a very deformed shape. The half-life of the 829.8-keV state is determined to be 265(27) ns in the present work. The new band indicates that the emptying of the upsloping g(9/2) orbital with K=9/2 is closely related to the strong prolate shapes of some bands in the Sr and Zr regions with Aapproximate to100.
