Abstract：
Exact eigen-energies and the corresponding wavefunctions of the interacting sl-boson system in U(2l+1) transitional region are obtained by using an algebraic Bethe ansatz with the infinite dimensional Lie algebraic technique. Numerical algorithm for solving the Bethe ansatz equations by using mathematica package is also outlined.
