High-spin yrast and yrare structures in 112In

Abstract

The high-spin states of 112In have been investigated with in-beam $ \gamma$ -ray spectroscopic methods using the 110Pd (7Li, 5n)112In reaction at a beam energy of 50MeV. A level scheme with 3 band structures has been established. The backbending associated with the alignment of a pair of g 7/2/d 5/2 neutrons has been found in the negative-parity yrast band. The configuration for the positive-parity yrare band has been assigned to $ \pi$ g 9/2 ⊗ $ \nu$ g 7/2 for the lower-spin states, and $ \pi$ g 9/2 ⊗ $ \nu$ h 2 11/2(g 7/2) for the higher-spin levels.
