The Calculation Of Astrophysical S Factors For E1 And E2 Capture Data Of C-12(Alpha,Gamma)O-16 Reaction At 300 Kev

The astrophysical S factors of E1 and E2 capture data of C-12(alpha,gamma) reaction at 300 keV have been calculated based on our recent determined ANC values of 6.92 MeV and 7.12 MeV states of O-16 using R-matrix. The S-factors are extrapolated into the range of burning temperature and the S-factors at 300 keV are S (E1)= (86 +/- 34) keV b and S (E2)= (60 +/- 33) keV b.
