Lifetimes of states in the negative-parity band, based on the ν (h 11 / 2) orbital in 103 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 J (2) / B(E2) values are found to be large (> 300 ħ 2 MeV - 1 (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.
