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.

Structure of nearly degenerate dipole bands in 108Ag

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

Antimagnetic Rotation in 101 Pd

The low-lying states of 108Ag near the I π = 6+ isomer have been investigated with the 11B + 100Mo reaction at 39 MeV beam energy. We aim at understanding the structure of the states near the isomer and identifying possible isomer depletion paths. From the γ–γ and γ–γ–γ coincidence analysis, spectroscopy of the excited states near the isomer has been carried out to establish new transitions and modification of the previously known level scheme. The present work suggests a total of three possible transitions at energies below 500 keV from the isomer to higher excited levels, whose subsequent decay can branch to the ground state. The spins and parities of these states have been established with angular correlation and polarization measurements. The branching ratios and multipolarities of the associated γ-rays were used in the estimation of the integral cross section for induced isomer depletion via these states. The experimental data have been compared to the results of projected Hartree–Fock calculations to understand the configurations of the levels.
