The C(C) Ne and C(C) Na reactions, which determine carbon burning in stars, have been measured from E = 2.7 MeV down to 0.8 MeV via the Trojan Horse Method off the deuteron in N. This range of energies is relevant for several astrophysical scenarios, from superburst ignition to hydrostatic burning. The measured astrophysical S(E) factors reveal several resonances, which are responsible for a very large increase of the reaction rate at the relevant temperatures.

Abstract
The C(C) Ne and C(C) Na reactions, which determine carbon burning in stars, have been measured from E = 2.7 MeV down to 0.8 MeV via the Trojan Horse Method off the deuteron in N. This range of energies is relevant for several astrophysical scenarios, from superburst ignition to hydrostatic burning. The measured astrophysical S(E) factors reveal several resonances, which are responsible for a very large increase of the reaction rate at the relevant temperatures.File in questo prodotto:
