- Abstract
The reaction C()O was investigated through the direct -transfer reaction (7Li,t) at 28 and 34 MeV incident energies. We determined the reduced -widths of the sub-threshold 2 and 1 states of O from the DWBA analysis of the transfer reaction C(7Li,t)O performed at two incident energies. The obtained result for the 2 and 1 sub-threshold resonances as introduced in the -matrix fitting of radiative capture and elastic-scattering data to determine the E2 and E1 -factor from 0.01MeV to 4.2MeV in the center-of-mass energy. After determining the astrophysic factor of C()O S(E) with Pierre Descouvement code, I determined numerically the new reaction rate of this reaction at a different stellar temperature (0.06 Gk-2 GK). The C()O reaction rate at T is [7.21] × 10 cm3 s mol. Some comparisons and discussions about our new C()O reaction rate are presented. The agreements of the reaction rate below T between our results and with those proposed by NACRE indicate that our results are reliable, and they could be included in the astrophysical reaction rate network.
