摘要: A deformed VMI-core plus two particles is considered as a simple model for even-even nuclei. In basis of three antisymmetrized wave functions, which representK=0-, 1-, 2- bands, the Hamiltonian this system diagonalized. After an additional minimalisation, must take place according to VMI-model, one gets energies yrast-band depending on VMI-parameters and further parameters, rule back-bending-behavior. Fitting these parameters with experimental data nearly total agreement between theory experiment obtained backbending nuclei158Er,160Er,162Er and166Yb.
