Identification of 9/2[404] band in 97Sr Academic Article uri icon


  • An excited rotational band including seven new transitions was identified in 97Sr from -- coincidences in the spontaneous fission of 252Cf. This new band, built on the 829.8-keV state, is interpreted as the 9/2[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 g9/2 orbital with K = 9/2 is closely related to the strong prolate shapes of some bands in the Sr and Zr regions with A 100.
