Abstract

The carbon-burning process in massive stars mainly occurs via the ¹²C +¹² C. However, at temperatures higher than 10⁹K and considering the increased abundance of ¹⁶O produced during the later stages of the heliumburning,the ¹²C+¹⁶O fusion can also become relevant. Moreover, ¹²C+¹⁶O also plays a role in the scenario of explosive carbon burning. Thus, the astrophysical energy region of interest ranges from 3 to 7.2 MeV in the center-of-mass frame. However, the various measurements of the cross-section available in the literature stop around 4 MeV, making extrapolation necessary. To solve this uncertainty and corroborate direct measurement we applied the Trojan Horse Method to three-body processes ¹⁶O(¹⁴N, α²⁴Mg)²H and ¹⁶O(¹⁴N, p²⁷Al)²H to study the ¹²C(¹⁶O, α)²⁴Mg and ¹²C(¹⁶O, p)²⁷Al reactions in their entire energy region of astrophysical interest. In this contribution, after briefly describing the method used, the experiment and the preliminary phases of the data analysis will be presented and discussed.
