The exact solvability of several nuclear models with non-degenerate single-particle energies is outlined and leads to a generalization of integrable Richardson-Gaudin models, like the su(2)-based fermion pairing, to any simple Lie algebra. As an example, the so(5)∼ sp(4) model of T=1 pairing is discussed and illustrated for the case of 64Ge with non-degenerate single-particle energies.
