Abstract
We describe the spectra of even-even N = Z nuclei in a formalism of quartets. Quartets are α-like four-body structures characterized by an isospin T = 0. The structure of the quartets is fixed 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 constructed via configuration-interaction calculations in the spaces built with these quartets. Some applications of this formalism are discussed for nuclei in the sd and pf shells. A good description of the low-lying spectra of these nuclei is achieved.
