C-12 +C-12 is the main reaction during core and shell carbon burning in massive stars, however, at temperatures higher than K-109 when most of the carbon is depleted and its abundance is lower than O-16, the C-12 +O-16 fusion can also become relevant. Moreover, C-12 +O-16 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 O-16(N-14, alpha Mg-24)H-2 and O-16(N-14, p(27)Al)H-2 to study the O-16(C-12, alpha)Mg-24 and O-16(C-12, p)Al-27 reactions.
