Possible antimagnetic rotational band and neutron alignment in In 113

High-spin states of In113 have been populated using the Pd110(Li7,4n)In113 reaction at beam energies of 38 and 50 MeV. More than 50 new γ transitions are observed in In113. Three previously observed magnetic dipole bands are extended to higher spin states, and several new E2 crossover transitions within the bands are observed in two of the dipole bands. A new positive-parity μI=2 band built on the πd5/2 configuration is established. The known μI=2 band is extended to 51/2+ state, and a gentle up-bend associated to the alignment of neutrons in the normal-parity νg7/2/d5/2 orbitals is found. The properties of this band are discussed based on the self-consistent tilted axis cranking relativistic mean-field model calculations. The predicted B(E2), deformation parameters β2 and γ, and J(2)/B(E2) ratios indicate that the μI=2 band based on the πg9/2-2g7/2 - ν(h11/2)2 and πg9/2-2g7/2 - ν(h11/2)2(g7/2/d5/2)2 configurations, has the characteristics of antimagnetic rotation. Furthermore, the two-shears-like mechanism for the possible antimagnetic rotational bands is examined by investigating the orientation of the angular momenta.
