Abstract
This work reports the first rotational bands observed in the neutron-deficient nucleus 231U. Excited states were populated in the 232Th(α,5n) reaction at a beam energy of 52 MeV. Coincident decay γ-rays were measured with the high-purity germanium detectors of the afrodite spectrometer array, in conjunction with a recoil detector to discriminate against the fission background. The bands are interpreted as the ground-state band ν[633]5/2+, yrast band ν[752]5/2-, and an excited band ν[631]3/2+. Configuration assignments are supported by Cranked Shell Model and B(M1)/B(E2) calculations. The excitation energy of the ν[752]5/2- bandhead is suggested to be 113.0 keV.
