High-J Proton H(11/2) And G(7/2) Intruder Bands In In-113

Excited states of(113)In have been populated through the heavy-ion fusion evaporation reaction(110)Pd(Li-7, 4n)In-113. A new band with the configuration of a protond(5/2)orbital is identified. Two Delta I= 2 intruder bands, built on the pi h(11/2)and the pi g(7/2)orbitals, have been extended to spins (63/2(-)hand (55/2(+))h, respectively. The negative-parity pi h(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 pi g(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)nu shell and the core rotation are investigated for the positive-parity pi g(7/2)band.
