The description of the ground-state magnetic properties of odd-mass nuclei is very informative in understanding of the complex structure of the deformed nuclei. The ground-state magnetic moments of most of the odd-A deformed nuclei have been measured by various experimental studies and there are numerous studies in the literature. However, many of the theoretical studies on magnetic moments and spin polarization effects affecting them are far from explaining these measured values. In this paper, the magnetic moments and effective spin g factors of 143,145,147 Sm isotopes in the lanthanides region of the periodic table were investigated within the framework of the Quasiparticle-Phonon Nuclear Model (QPNM) based on the Lagrange Multiplier Method for the first time. Spin-spin interaction parameters (χ) were determined by comparing theoretical and experimental values of magnetic moments of the related isotopes and these interactions were found to have an isovector character q = −1. It has been observed that the ground-state structures of the studied isotopes are weakly affected by quasiparticle⊗phonon interactions and the contribution of these interactions (G K0v iµ values) to the ground-state wave functions is quite small (around 0.01%). Theoretical explanation of the renormalization of spin gyromagnetic factor is one of the most important problems of nuclear structure physics. The results obtained in this study for the effective spin gyromagnetic factor g ef f. s g τ s also agree with the phenological value g ef f.s = (0.5 − 0.7)g τ s .

“…of this configuration for the neutron and proton, as was pointed out by Hisatake [4], are identified as 3/2 and 5/2, respectively. The determination of the Nilsson quantum numbers of ground state of the odd-odd 138,140 Pr nuclei will serve as a basis for calculating various characteristics such as beta decay [11], magnetic moment [12][13][14][15][16] and magnetic dipole transitions [17][18][19][20][21][22][23] of even and odd mass nuclei.…”

In this work, we have determined the Nilsson quantum numbers of the ground state of the odd-odd 138,140 Pr nucleus for the first time. To achieve it, several low energy neutron-proton two quasiparticle levels have been calculated in 138,140 Pr nuclei using deformed Woods-Saxon potential basis. The Gamov-Teller β (+) decay transition matrix elements from these levels to the ground state of the neighbor 138,140 Ce nuclei and log f t values have been calculated. From the comparison of theoretical and experimental log f t values and neutron-proton K quantum numbers the ground state Nilsson quantum numbers of the odd-odd isotopes have been determined as {n [402]3/2− p[413]5/2} 1 + for two isotopes.
