Observation of anti-magnetic rotations in 104Pd

Abstract

The electric quadrupole transition rates for the high spin yrast states of 104 Pd have been measured by using the DSAM technique. These values decrease with the increase of angular momentum which is a signature of anti-magnetic rotation. A numerical calcula- tion based on semi-classical particle plus rotor model for anti-magnetic rotation gives a good description of the experimental routhian and the transition rates. This is the first observation of AMR in a nucleus other than Cadmium.
