Resonant behavior of theMg24(O16,C12)Si28reaction

Abstract
The Mg24(O16, C12)Si28 reaction has been studied over the energy range 26.3<Ec.m.<32.4 MeV. Angular distributions with 4.5°θc.m.50° were measured at nine different energies in this range and an excitation function was measured over a wider range at θc.m.90°. The results of the present measurements, together with previously measured excitation functions at 0° and 180°, are analyzed within the framework of two resonances, at 27.6 and 30.8 MeV, added to a direct reaction background. Probable spin assignments for the two resonances are J=20 (27.6 MeV) and J=23 (30.8 MeV).
