Abstract
Excited states of 113In have been populated through the heavy-ion fusion evaporation reaction 110Pd(7Li, 4n)113In. A new band with the configuration of a proton d5/2 orbital is identified. Two ΔI = 2 intruder bands, built on the πh11/2 and the πg7/2 orbitals, have been extended to spins (63/2−ħ and (55/2+)ħ, respectively. The negative-parity πh11/2 intruder band shows a smooth increase in aligned spin, which is attributed to a strong proton-neutron interaction. The properties of the positive-parity πg7/2 band are discussed based on tilted axis cranking model calculations, and the features of the antimagnetic rotation for this band are shown after backbend. Furthermore, the contributions of the two-shears-like mechanism, the neutron (gd)ν shell and the core rotation are investigated for the positive-parity πg7/2 band.
