High Spin States of ¹¹³In

Level structures of ¹¹³In are studied through the fusion-evaporation reaction ¹¹⁰Pd(⁷Li,4n)¹¹³In at a beam energy of 50 MeV. Two new bands are established for the first time. Here the ΔI = 2 band based on proton excitation is assigned to the πg_9/2^-2⊗νh_11/2²d_5/2 configuration. In addition, the backbending associated with the additional aligned h_11/2 neutron pair is found in the negative parity yrast band. The experimental results are compared with self-consistent tilted axis cranking relativistic mean field calculations. Several decay paths of the πh_11/2 intruder band are established, by which the level energies and spins of the πh_11/2 intruder band are determined. The bandcrossing delay of the πh_11/2 intruder bands around the Z=50 shell and the dynamic moment of inertia of the πg_9/2^-1⊗νh_11/2² bands in ^{113,115,117,119}In are studied systematically.
