The wave function factorization method determines an optimal basis of correlated proton and neutron states, and accurately approximates low-lying shell-model states by a rather small number of suitable product states. The optimal basis states result from a variational principle and are the solution of relatively low-dimensional eigenvalue problems. The error involved in this truncation decreases exponentially fast as more basis states are included.
