C-12(Ne-20, O-16)O-16 Alpha-Transfer Reaction And Astrophysical S-Factors At 300 Kev

The C-12(Ne-20, O-16)O-16 reaction has been used for the first time to determine ANC of 16 0 levels. The C-12(Ne-20, O-16)O-16 alpha-transfer angular distributions are measured at E-lab = 150 MeV and used to determine the ANC of the ground, 6.05 MeV (0(+)), 6.13 MeV (3(-)), 6.92 MeV (2(+)) and 7.12 MeV (1(-)) states of O-16. The ANC values are C-2 (0(+)) = (22.2 +/- 7.1) x 10(4) fm(-1), C-2 (0(+)) = (1.40 +/- 0.54) x 10(6) fm(-1) C-2(3(-)) = (2.30 +/- 0.92) x 10(4) fm(-1), (2+) = (1.07 +/- 0.32) x 10(10) fm(-1) and C-2 (1(-)) = (32.29+10.14) x 10(28) fm(-1). Astrophysical S-factors at 300 keV are extracted {S-E1(300) = (79.18 +/- 26.60) keV b and S-E2(300) = (52.51 +/- 24.3) keV b} using these ANC values by R-matrix theory.
