Résumé :

The 16O spectrum is investigated microscopically in a multiconfiguration generator-coordinate basis, including the α + 12C(0+), α + 12C(2+), p + 15N( 1 2-) and n + 15O( 1 2-) configurations. This choice allows a microscopic description of T = 1 states and of isospin impurities in low-lying states of the 16O nucleus. The model reproduces most of the T = 0 and T = 1 states below 14 MeV excitation energy. Different bands are suggested, for which valuable experimental candidates exist. A satisfactory agreement with experiment is obtained for the El, E2 and Ml transition probabilities. © 1987.
