Local coordinate systems are chosen for each quadruple of atoms relative to a four-center integral, in order to avoid linear combinations of orbitals when symmetry operations perform on an orbital. This choice can utilize the complete molecular symmetry to attain the optimal number of symmetry-uniqu
## 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.
