Negative parity energy states in 121–131 La have been studied using Projected Shell Model (PSM). Some nuclear structure properties like yrast spectra, back-bending in moment of inertia, reduced transition probabilities and band diagrams have been described. The experimental feature of the co-existence of prolate–oblate shapes in 125–131 La isotopes has been satisfactorily explained by PSM results. Comparison of the theoretical data with their experimental counterparts has also been made. From the calculations, it is found that the yrast states arise because of multi-quasiparticle states.

Structure Properties

The change of magnetoresistance in dependence on the strength of the magnetic induction is examined theoretically for several heterostructures taken as examples. Different temperatures of the examined samples, concentrations of the electron or hole carriers, and band structure properties are then involved. A general result is that a linear increase of magnetoresistance as a function of the magnetic induction should be obtained for all samples. This finds its counterpart in the behaviour of the experimental data. The ratios of the theoretical slopes of increase to the experimental ones range between 0.1 and 11, but the average ratio amounts to less than 1.8.

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.
