摘要：
Exact eigen-energies and the corresponding wavefunctions of an interacting sl-boson system in a U(2l+1) <----> O(2l + 2) transitional region are obtained by using the Bethe ansatz within an infinite-dimensional Lie algebra. A numerical algorithm for solving the Bethe ansatz equations is introduced. As an example, spectra for the U(3) <----> O(4) transitional region of the U(4) Vibron model are analysed.
