Abstract
Lifetimes of states in the negative-parity band, based on the \(\nu (h_{11/2})\) orbital in \(^{103}\hbox {Pd}\), have been measured in the spin range from 27/2 to 39/2 using the Doppler-Shift Attenuation Method. The inferred B(E2) values are observed to decrease with increasing angular momentum and \({\mathcal {J}}^{\text {(}2\text {)}}/\)B(E2) values are found to be large (> 300 \(\hbar ^2\hbox {MeV}^{-1}\hbox {(eb)}^{-2}\)). These observations along with calculations based on the semiclassical particle-rotor model approach suggest that antimagnetic and collective rotation, along with gradual neutron alignment are responsible for angular momentum generation in the band under consideration.
