Microscopic Description of g Factors and M1 Properties in Platinum Isotopes
1999
Starting from the shell model configurations, valence nucleon effective interactions and fermion M1 transition current density operator, the counterparts in the proton-neutron interacting boson model (sdIBM-2) of the fermion Hamiltonian and M1 transition current density operator are derived microscopically with the help of Dyson expansion technique. The boson g factors are abstracted from the boson M1 transition current density operator. Spectra, g factors of states and M1 matrix elements between and are calculated for the even 192-198Pt isotopes in the sdIBM-2. The theoretical results fit experimental data quite well.
