Abstract
The nuclear mean field plus stare-dependent pairing problem is studied by u sing the Bethe ansatz method. It is shown that the Hamiltonian can be expan ded in terms of generators of the infinite-dimensional Lie algebra <(SU(2)) over cap> without central extension. Exact solutions for excited energies a nd the corresponding eigenstates of the nuclear pairing problem are derived through the Bethe ansatz equations.
