High Spin States of113In
2012
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−29/2⊗νh211/2d5/2 configuration. In addition, the backbending associated with the additional aligned h11/2 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 πh11/2 intruder band are established, by which the level energies and spins of the πh11/2 intruder band are determined. The bandcrossing delay of the πh11/2 intruder bands around the Z = 50 shell and the dynamic moment of inertia of the πg−19/2⊗νh211/2 bands in 113,115,117,119 In are studied systematically.
