description

This chapter describes the configuration mixing of particle-hole excitations in doubly magic nuclei. The discussion is confined to one-particle-one-hole excitations within the simplest scheme of configuration mixing, namely the Tamm-Dancoff approximation (TDA). We show that the TDA arises from a variational principle and leads to diagonalization of the residual Hamiltonian in a basis of particle-hole excitations of the particle-hole vacuum.
