Antimagnetic rotation in Cd isotopes

Antimagnetic rotation is a manifestation of Shears mechanism. In this specific case, the perpendicular components of the dipole moments of the two shears cancel each other due to the symmetry of the structure which leads to the absence of M1 transitions. The talk will cover the recent data on 110Cd and a model based on classical particle plus rotor. This model has been used to explore the underlying systematics of even-even Cd isotopes and a self consistent picture for the observed behaviours of 106,108,110Cd will be discussed. This systematic study also helps to estimate the strengths of particle-hole and hole-hole interactions of this mass region. The applicability of this model to the odd-odd Cd isotopes, namely 105,107,109Cd, will also be discussed. (author)
