Chiral bands in 105Rh

Abstract

The 105Rh nucleus has been studied by in-beam γ spectroscopy with the heavy-ion fusion-evaporation reaction 100Mo(11B, α2nγ) at 43 MeV. A rich variety of structures was observed at high and low spin, using γ - γ - t and γ - γ - particle coincidences and directional correlation ratios. Four magnetic dipole bands have also been observed at high spin. Two of them are nearly degenerate in excitation energy and could be chiral partners, as predicted by Tilted Axis Cranking calculations.
