Small quadrupole deformation for the dipole bands in 112In

High spin states in In-112 were investigated using the Mo-100(O-16, p3n) reaction at 80 MeV. The excited level has been observed up to 5.6 MeV excitation energy and spin similar to 20 (h) over bar h with the level scheme showing three dipole bands. Polarization and lifetime measurements were carried out for the dipole bands. Tilted axis cranking model calculations were performed for different quasiparticle configurations of this doubly odd nucleus. Comparison of the calculations of the model with the B(M1) transition strengths of the positive-and negative-parity bands firmly established their configurations.
