- Abstract
This work reports the first rotational bands observed in the neutron-deficient nucleus 231 U. Excited states were populated in the 232 Th(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.
