โœฆ Synopsis

The differential cross sections for the reactions 9Be(lยฐB, gBe)lยฐB at an incident lยฐB energy of 100 MeV and leO(SHe, d)~rF*(0.495 MeV, 1/2 +) at an incident SHe energy of 29.75 MeV were measured. By normalizing the theoretical DWBA proton exchange cross sections to the experimental ones, the asymptotic normalization coefficients (ANC's) for the virtual decays lยฐB ~ 9Be +p and 1~F*(0.495 MeV) --* 180 +p have been found. These ANC's are used to calculate the S(0)-factors for the direct radiative captures 9Be + p lยฐB + 3' and 160 + p --~ lrF*(0.495 MeV)

The 13 C(p, ฮณ ) 14 N radiative capture reaction is analyzed within the R-matrix approach with the aim to determine the astrophysical S factor. The low-energy astrophysical S factor has important contributions from both resonant and nonresonant captures. The contribution of the nonresonant component
