| Summary: | We describe deformed N = Z nuclei in a formalism of α-like quartets. Quartets are constructed variationally by resorting to the use of proper intrinsic states. Various types of intrinsic states are introduced which generate different sets of quartets for a given nucleus. Energy spectra are generated via configurationiteraction calculations in the spaces built with these quartets. The approach is applied to 24Mg and 28Si in the sd shell and to 48Cr in the p f shell. In all cases a good description of the low-lying spectra is achieved. As a peculiarity of the approach, a close correspondence is observed between the various sets of quartets employed and the occurrence of well defined band-like structures in the spectra of the systems under study. |
