Abstract
he fusion reactions C12(C12,a)Ne20 and C12(C12,p)Na23 have been studied from E=2.10 to 4.75 MeV by ?-ray spectroscopy. The deduced astrophysical factor exhibits new resonances at E=3.0MeV, in particular, a strong resonance at E=2.14MeV, which lies at the high-energy tail of the Gamow peak. The resonance increases the present nonresonant reaction rate of the a channel by a factor of 5 near T=8×108K.File in questo prodotto:
