We use the Generator Coordinate Method to investigate some nuclei between A=12 and A=16, in a multicluster model. The microscopic wave functions are defined from cluster wave functions, involving three α particles and any s-shell nucleus. The α clusters are located at the apexes of an equilateral triangle, and form the basis of a tetrahedral structure, with the additional s cluster at the top of its height. Optimal configurations are determined for the 12C, 13C, 14C, 15N and 16O nuclei. We show that, with respect to the more usual shell-model approach, the multicluster description significantly improves the binding energy and the spectroscopic properties. Future applications to reactions of astrophysical interest are discussed.
