## Abstract It is pointed out that the density matrices of the ground state contain valuable information concerning the calculation of particleβhole excited states. As an illustration, results on the nuclei ^16^O, ^20^Ne, and ^28^Si are presented, using small model spaces.
## Abstract A reduced first order density matrix for the Be ground state is computed from an extensive configuration interaction (CI) wave function. A sequence of increasingly accurate CI wave functions Ξ¦__~q~__ converging towards the exact Ξ¨ is used to assess the quality of the results which inclu
