摘要
High spin states in the odd-A nucleus 113In have been investigated using the re-action 110Pd（7Li,4n） at a beam energy of 50 MeV. A new positive parity dipole band with the configuration of π（g9/2）-1ν（h11/2）2ν（g7/2）2 is established. The effective interaction V（θ） values of this band have been successfully described by a semiclassical geometric model based on shear mechanism, which show that the dipole band has the characteristics of magnetic rotation. In addition the collective rotational angular momentum for this band is extracted. The results show that the core contribution increases gradually with the increase of the rotation frequency.
