The Pt isotopes are studied in the boson-plus-fermion-pair model. The li13/2, 1h9/2 and 2f5/2 fermion orbitals are included in the model space. Isotopes quite near to the closed shells are included in the calculation. It was found that significant influences to the energy levels could be produced by the small mixtures from the fermion-pair configurations. The energy spectra and moment of inertia backbendings can he reproduced quite well. The calculated B(E2) values show prominent dips at the onsets of different, fermion-pair configurations.
