Abstract
The reaction (p,γO 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 excited state in . 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, /Γ, for this state. This method does not require the use of radioactive as either a beam or a target, neither of which is at present technically feasible. Using the He,tO reaction, the total width of this state has been measured to be Γ=38.1±1.8 keV.
