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