Abstract

Lifetimes of states in a negative-parity band involving the νh11/2 orbital in Pd100 have been determined through Doppler shift attenuation method (DSAM) measurements performed using Indian National Gamma Array (INGA) spectrometer. The measured quadrupole transition rates, B(E2), exhibit a decreasing behavior with increasing angular momentum and with large observed (2)/B(E2) values. The experimental observations and semiclassical particle-rotor model calculations favor the antimagnetic rotation (AMR) phenomenon based on the π(g9/2)4ν[h11/2(g7/2)3] configuration for the negative-parity band in the Pd100 isotope.
