摘要：

A new microscopic method has been developed in the framework of the Quasiparticle-Phonon Nuclear Model (QPNM) in order to investigate spin polarization effects on the magnetic properties such as magnetic moment. intrinsic magnetic moment and effective g(s) factor of the ground state of odd-mass Er157-167 isotopes. The calculations were performed using both Tamm-Dancoff Approximation (TDA) and Quasi-particle Random-Phase Approximation (QRPA). Reasonably good agreement has been obtained between the QRPA results and the relevant experimental data. Furthermore the variation of the intrinsic magnetic moment g(K) values with the mass number A exhibits similar behavior for both theoretical and experimental results. From the compression of the calculated intrinsic magnetic moment values with the experimental data the spin spin interaction parameter has been found as chi = (30/A) MeV for odd-mass Er157-167 isotopes. Our results clarify the possibility of using this new method to describe the magnetic properties of odd-mass deformed nuclei. (C) 2012 Elsevier B.V. All rights reserved.
