Description
Summary:Excited states of 113 In have been populated through the heavy-ion fusion evaporation reaction 110 Pd( 7 Li, 4n) 113 In. A new band with the configuration of a proton d 5/2 orbital is identified. Two Δ I = 2 intruder bands, built on the πh 11/2 and the πg 7/2 orbitals, have been extended to spins (63/2 − ħ and (55/2 + ) ħ , respectively. The negative-parity πh 11/2 intruder band shows a smooth increase in aligned spin, which is attributed to a strong proton-neutron interaction. The properties of the positive-parity πg 7/2 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 πg 7/2 band.
