Abstract

Lifetimes of states in the negative-parity band, based on the $\nu (h_{11/2})$ orbital in ${}^{103}\text{Pd}$, 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 ${ħ}^2{\text{MeV}}^{-1}{\text{(eb)}}^{-2}$). 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.
