Astrophysical S factor for the radiative capture N-12(p,gamma)O-13 determined from the N-14(N-12,O-13)C-13 proton transfer reaction
Original language description
The cross section of the radiative proton capture reaction on the drip line nucleus N-12 was investigated using the asymptotic normalization coefficient (ANC) method. We have used the N-14(N-12,O-13)C-13 proton transfer reaction at 12 MeV/nucleon to extract the ANC for O-13 -> N-12+p and calculate from it the direct component of the astrophysical S factor of the N-12(p,gamma)O-13 reaction. The optical potentials used and the distorted-wave Born approximation analysis of the proton transfer reaction arediscussed. For the entrance channel, the optical potential was inferred from an elastic scattering measurement carried out at the same time as the transfer measurement. From the transfer, we determined the square of the ANC, C-p1/2(2)(O-13(g.s.))=2.53 +/- 0.30 fm(-1), and hence a value of 0.33(4) keV b was obtained for the direct astrophysical S factor at zero energy.
Czech name
Astrofyzikální S faktor radiačního záchytu 12N(p, ? )13O určený z reakce přenosu protonu 14N(12N, 13O)13C
Czech description
Metodou asymptotických normalizačních koeficientů byl určen astrofyzikální S-faktor radiačního záchytu 12N(p, ? )13O při nulové energii. Pro přímý proces byla vyvozena hodnota S(0) ( 13Og.s.) = 0.33(4) keVb, která vede v důsledku interference přímého procesu s rezonančním záchytem ke zvýšení celkového astrofyzikálního faktoru na hodnotu S(0) = 0.42(6) keVb.
