摘要：

The exact solution of theU(5)-O(6) transitional description in the interacting boson model with two-particle and two-hole configuration mixing is derived based on the Bethe ansatz approach. The Bethe ansatz equations are provided to determine the model's eigenstates and corresponding eigen-energies.N= 2 andN= 4 cases are considered as examples to demonstrate the solution features. As an example of the application, some low-lying level energies andB(E2) ratios of(108)Cd are fitted and compared with the corresponding experimental data.
