Structure of Dipole Bands in 112In: Through Lifetime Measurement

High-spin states of the ¹¹²In nucleus have been populated via ¹⁰⁰Mo(¹⁶O, p3n) reaction at 80 MeV beam energy. Lifetimes of excited states of dipole bands have been measured using Doppler-shift attenuation method. The B(M1) transition rates deduced from the measured lifetimes show a rapid decrease with increasing angular momentum. The decrease in B(M1) values are well accounted by the prediction of tilted axis cranking calculations. These measurements confirm the presence of shears mechanism in this nuclei.
