12C(20Ne, 16O)16O α-transfer reaction and astrophysical S-factors at 300keV

The [Formula: see text]C([Formula: see text]Ne, [Formula: see text]O)[Formula: see text]O reaction has been used for the first time to determine ANC of [Formula: see text]O levels. The [Formula: see text]C([Formula: see text]Ne, [Formula: see text]O)[Formula: see text]O [Formula: see text]-transfer angular distributions are measured at [Formula: see text][Formula: see text]MeV and used to determine the ANC of the ground, 6.05[Formula: see text]MeV ([Formula: see text]), 6.13[Formula: see text]MeV ([Formula: see text]), 6.92[Formula: see text]MeV ([Formula: see text]) and 7.12[Formula: see text]MeV ([Formula: see text]) states of [Formula: see text]O. The ANC values are [Formula: see text] [Formula: see text] [Formula: see text], [Formula: see text] [Formula: see text], [Formula: see text] [Formula: see text], [Formula: see text] [Formula: see text] and [Formula: see text] [Formula: see text]. Astrophysical S-factors at 300[Formula: see text]keV are extracted [Formula: see text]) keV b and [Formula: see text] keV b[Formula: see text] using these ANC values by R-matrix theory.
