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 ^192,190,188 Os isotopes. Present theoritical results fit experimental data quite well.
