Abstract

The high-spin states of ¹¹²In have been investigated with in-beam -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 g _9/2 ⊗ g _7/2 for the lower-spin states, and g _9/2 ⊗ h ² _11/2(g _7/2) for the higher-spin levels.
