The projected configuration interaction method starts from a collection of mean-field wave functions and builds up correlated wave functions of good symmetry. It relies on the generator coordinator method techniques, but it improves the past approaches by a very efficient method of selecting the basis states. We use the same realistic Hamiltonians and model spaces as the configuration interaction (CI) method and compare the results with the full CI calculations in the sd and pf shell. Examples of 24Mg, 28Si, 48Cr, 52Fe, and 56Ni are discussed.
