Abstract

The reaction N13(p,γ)14O is important in the hot-CNO cycle. At the energies of astrophysical interest, the rate of this reaction is dominated by capture through an l=0 resonance corresponding to the 5.17 MeV Jπ=1 excited state in O14. The contribution of this resonance to the total cross section can be determined from a measurement of the total width, Γ, and the γ-decay branching ratio, Γγ/Γ, for this state. This method does not require the use of radioactive N13 as either a beam or a target, neither of which is at present technically feasible. Using the N14(3He,t)14O reaction, the total width of this state has been measured to be Γ=38.1±1.8 keV.
