Small quadrupole deformation for the dipole bands in 112In

Abstract

High spin states in 112In were investigated using the 100Mo(16O,p3n) reaction at 80 MeV. The excited level has been observed up to 5.6 MeV excitation energy and spin ∼20 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. © 2012 American Physical Society.
