Abstract

¹²C +¹² C is the main reaction during core and shell carbon burning in massive stars, however, at temperatures higher than 10⁹K when most of the carbon is depleted and its abundance is lower than ¹⁶O, the ¹²C +¹⁶ O fusion can also become relevant. Moreover, ¹²C +¹⁶ O reaction can ignite also in the scenario of explosive carbon burning. The astrophysical energy region of interest thus ranges from 3 to 7.2 MeV in the center-of-mass frame. There are various measurements of the cross-section available in the literature, however, they all stop around 4 MeV, making extrapolation necessary at lower energies. To try to solve this uncertainty and corroborate direct measurement the Trojan Horse Method was applied to three-body processes ¹⁶O(¹⁴N, α²⁴Mg)²H and ¹⁶O(¹⁴N, p²⁷Al)²H to study the ¹⁶O(¹²C, α)²⁴Mg and ¹⁶O(¹²C, p)²⁷Al reactions.
