Systematics of antimagnetic rotation in even–even Cd isotopes

Abstract A model based on classical particle plus rotor has been used to explore the underlying systematics of even–even Cd isotopes and a self consistent picture for the observed behaviors of 106, 108, 110 Cd has been reported. This systematic study also helps to estimate the strengths of particle–hole and hole–hole interactions of this mass region.

Possibility of Antimagnetic Rotation in odd-A Cd isotopes

The classical particle plus rotor model for antimagnetic rotation (AMR) has been used to investigate the possibility of observation of AMR in the high spin levels of

Emergence of principal axis rotation in 110Ag

High-spin states of the 112In nucleus have been populated via 100Mo(16O, p3n) reaction at 80 MeV beam energy. Lifetimes of excited states of dipole bands have been measured using Doppler-shift attenuation method. The B(M1) transition rates deduced from the measured lifetimes show a rapid decrease with increasing angular momentum. The decrease in B(M1) values are well accounted by the prediction of tilted axis cranking calculations. These measurements confirm the presence of shears mechanism in this nuclei.

Comment on “Evidence of antimagnetic rotation in odd-A105Cd”

At IUAC-INGA, our group has studied four neutron rich nuclei of mass-110 region, namely 109,110Ag and 108,110Cd. These nuclei provide the unique platform to study the interplay between Tilted and Principal axis rotation since these are moderately deformed and at the same time, shears structures are present at higher spins. The salient features of the high spin behaviors of these nuclei will be discussed which are the signatures of this interplay.

Band crossing in a shears band of 108Cd

The level lifetimes have been measured for a Shears band of 108 Cd which exhibits bandcrossing. The observed level energies and B(M1) rates have been successfully described by a semi-classical geometric model based on shear mechanism. In this geometric model, the bandcrossing in Shears
