Abstract
The distribution of the E2 strength in 12C and 16O nuclei is investigated by inelastic scattering of 3He. The giant quadrupole resonance is found to be splitted into several states in both nuclei and exhausts 31 % and 37 % of the quadrupole energy weighted sum rule (EWSR) in 12C and 16O respectively.
Résumé
La distribution des transitions quadrupolaires dans les noyaux 12 C et 16O est étudiée par diffusion inélastique de 3He. La résonance quadrupolaire géante présente une structure fine distribuée sur plusieurs niveaux individuels dans les deux noyaux, elle épuise 31 % et 37 % de la règle de somme E2 (EWSR) dans 12C et 16O respectivement.
