abstract

  • © 2008 American Institute of Physics. The angular distributions of the 15N(3He,d)16O reaction were measured with the aim to determine the direct capture rate of the astrophysical reaction 15N(p, γ)16O by deducing asymptotic normalization coefficients (ANC). The 15N(p,γ)16O reaction is a part of the CNO cycle having importance in the nucleosynthesis of the N and O isotopes. The measurement was carried out on the cyclotron U120M of NPI CAS at the energy 25.74 MeV of 3He ions in a gas chamber containing the high purity 15N isotope. The preliminary results of corresponding spectroscopic factors and ANC's were used for the estimation of the S-factor for the direct capture 15N(p,γ)16O. Using the widths of the resonances ER = 312 and 962 keV, the total S-factor was determined within the framework of the R-matrix approach.
