Abstract

The spectroscopy of Ge71 has been investigated via the fusion-evaporation reaction Ge74(α,α3n)Ge71. Collective structures including a rotational band built on the 15/2- octupole state in Ge71 have been established. The observation of strong E1 transitions and the well-behaved rotational sequence built on the 15/2- octupole state provide the first experimental evidence of an octupole rotational band in Ge isotopes, suggesting an enhanced octupole correlation around N=40 in the A≈70 region. A newly developed semimicroscopic cluster model provides a good description of the octupole characteristics of Ge71.
