The high-spin states of 108 Ag have been studied by the in-beam γ spectroscopy with the reaction 104 Ru (7 Li ,3n)108 Ag at a beam energy of 33 MeV. The previously known positive-parity band structures have been extended up to higher spins. Their configurations are discussed based on alignments, band-crossing frequencies, and B(M1)/B(E2) ratios.

High spin states in the isotope 122Xe  were populated using the reaction 96Zn(30Si,2n)122Xe at a beam energy of 135 MeV. The subsequent γ-ray deexcitation was studied using γ-ray spectroscopic methods. The analysis of γ-γ coincidences has revealed two new structures of competing dipole and quadrupole transitions. The highest states of a positive parity band provide characteristics consistent with an approach to band termination.

Energy levels in 149Tb have been studied by the 142Nd (10B,3n) reaction using 54 MeV 10B beams from the McMaster University FN accelerator. Excitation functions, angular distributions, prompt γ–γ coincidence, electron conversion, and linear polarization measurements were obtained. On the basis of these measurements we have identified two rotaition-aligned πh11/2 bands, a negative parity band up to spin 27/2−, and a positive parity band up to spin 27/2+. The energy spacings between levels in these bands strongly resemble those in the ground state and the 3− octupole band of the adjacent 148Gd core nucleus. Other high spin positive parity states up to spin of 41/2 are also observed. These high spin states show some evidence of rotational structure in 14 9Tb.

Structure Properties

The positive parity band structure of odd mass neutron-rich 97 – 103 Y and 99 – 105 Nb nuclei has been studied using microscopic technique known as the projected shell model (PSM) with the deformed single-particle states generated by the standard Nilsson potential. The nuclear structure properties like yrast spectra, energy splitting, moment of inertia, rotational frequencies and reduced transition probabilities B(M1) and B(E2) have been calculated and their comparison with the available experimental data has been made. A shape evolution has also been predicted in these isotopes as one moves from 97 Y to 99 Y and 99 Nb to 101 Nb . The PSM calculations also demonstrate the multi-quasiparticle structure in these nuclei.
