Investigations of the magnetic dipol excitations of the odd-mass 151-159Eu and 151-161Gd

In this thesis, the ground state magnetic properties and magnetic dipole excitations of rare earth elements 151-159Eu and 151-161Gd nuclei have been theoretically investigated in framework of the QPNM (Quasiparticle Phonon Nuclear Model) for the first time. The theoratical values of the ground state magnetic properties such as intrinsic magnetic moment, effective spin gyromagnetic factor and magnetic moment were compared with the avaliable experimental data and the spin-spin interaction parameter was determined for each investigated nuclei. The results of QPNM calculations were also compared with the results of KPM (Kuliev-Pyatov Method), SPM (Single Particle Model) and QTDA (Quasiparticle Tamm-Dancoff Approximation). The magnetic dipole excitations in these nuclei were also theoretically investigated by using RI-QPNM (Rotation Invariant Quasiparticle Phonon Nuclear Model). RI-QPNM model makes it is possible to restore of the broken rotational symmetry of nuclear hamiltonien. Due to the self-consistency of restoration forceses, they contain no arbitrary parameters. The results of calculations are compared with the available experimental data.
