Abstract

High-spin states in Rh103 have been studied using the Mo100(7Li,4nγ) reaction at 45 MeV. The in-beam techniques employed included relative γ-ray excitation functions, γ-γ coincidences, and γ-ray angular distribution measurements. Low-lying collective bands built on the 1g9/2 and 2p1/2 quasiproton states show large signature splitting. At higher excitation energies (2.346 and 3.399 MeV), two strong ΔI=1 cascades are also observed with small signature splitting. These latter bands probably arise from three quasiparticle configurations. The one quasiparticle bands are interpreted within the framework of the axially symmetric rotor-plus-particle model with a variable moment of inertia, the generalized particle-asymmetric-rotor model, and the interacting boson-fermion model. High-spin features of Rh103 are compared with the predictions of the cranked shell model. All of the models indicate that Rh103 is a soft nucleus which exhibits shape coexistence.
