摘要：

Nilsson mean-field plus the extended pairing model for well-deformed nuclei is applied to describe rare-earth nuclei. Binding energies, even-odd mass differences of Er, Yb, and Hf isotopes are calculated systematically in the model with proton pair excitation frozen approximation. Compared with the corresponding experimental data, the results obtained from the standard pairing model with BCS approximation, and the nearest orbit pairing model, it is shown that the extended pairing model is better than the other two models in description of rare-earth nuclei.
