Abstract：
From the shell model configurations, valence nucleon effective interactions and fermion E2 transition operator, the sdgIBM-1 Hamiltonian and the boson E2 transition operator are microscopically deduced in accordance with an approach which is based on Dyson boson expansion. The spectra and the reduced E2 transition matrix elements are calculated for the even ^190─200Pt isotopes. Present theoritical calculations fit experimental data or phenomenological results fairly well.
