Systematics of Anti magnetic rotation in even-even Cd isotopes

TL;DR

This paper investigates the anti-magnetic rotation phenomenon in even-even Cd isotopes, analyzing high-spin states and lifetimes to understand their unique angular momentum behaviors.

Contribution

It introduces a classical particle-rotor model to explain the systematics of anti-magnetic rotation in $^{110}$Cd and its differences from neighboring isotopes.

Findings

B(E2) values decrease with increasing angular momentum

$^{110}$Cd shows distinct alignment behavior

Model successfully explains observed systematics

Abstract

The lifetimes for the high spin levels of the yrast band of $^{110}$Cd has been measured. The estimated B(E2) values decrease with increase in angular momentum. This is the characteristic of Anti magnetic rotation as reported in $^{106,108}$Cd. However, alignment behavior of $^{110}$Cd is completely different from its even-even neighbors. A model based on classical particle plus rotor has been used to explore the underlying systematics and develop a self consistent picture for the observed behavior of these isotopes.
