C13(α,n)O16Reaction Cross Section between 1.95 and 5.57 MeV

The ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}(\alpha ,n){}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ total cross section has been determined for the incident $\alpha$-particle energy range 1.95 to 5.57 MeV using a $4\pi$ neutron detector. The total cross section of the inverse reaction ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(n,\alpha ){}_{}{}^{13}{}_{}{}^{}\mathrm{C}$ has been calculated by applying the reciprocity theorem. The total level widths for 16 levels, and the partial widths ${\Gamma }_{\alpha }$ and ${\Gamma }_n$ along with the reduced widths ${{\gamma }_{\alpha }}^2$ and ${{\gamma }_n}^2$ for the levels corresponding to the 2.68, 2.81, 3.72, and 4.62-MeV resonances, have been determined.
