摘要
From the shell model configurations, valence nucleon effective interactions and fermion E2 transition operator, the sdgIBM-1 Hamiltonian and boson E2 transition operator are derived micoscopically with the help of Dyson boson expansion technique. Spectra and reduced E2 matriX elements are calculated for the 192,190,188Os isotopes. Present theoritical results fit experimental data quite well.
