Observation of breakup transfer process for the bound states of [sup 16]O populated from [sup 12]C([sup 6]Li,d) reaction at 20 MeV

The study of12C(α,γ) astrophysical reaction using12C(6Li,d) and12C(7Li,t) reaction at 20 MeV and in the framework of the potential model

“…In two separate experiments angular distributions were measured for the 12 C( 6,7 Li,d/t) reactions at 20 MeV populating the discrete states of 16 O. The analysis of the 12 C( 6 Li,d) reaction indicated the effect of very strong breakup coupling for the population of the 16 O ground state [4]. In this respect the analysis of the 12 C( 7 Li,t) reaction is interesting because 7 Li has a higher breakup threshold (2.47 MeV) in comparison to 6 Li.…”

“…It is one of the main inputs in the theoretical model for extrapolation and is generally obtained by fitting the available experimental S-factor data [2]. The reduced alpha width of 16 O can be additionally constrained by 12 C(α,α) elastic scattering data and alpha transfer reaction on 12 C. The alpha transfer reactions such as 12 C( 6 Li,d) [3,4] and 12 C( 7 Li,t) [5,6] at various incident energies have been used to determine the reduced alpha width of 16 O states. The Trojan Horse method has been also used to study the 12 C(α,γ) reaction [7].…”
