Abstract

The explosive burning of ¹⁷O, which exhibits resonance at E _R^lab = 190 keV in the ¹⁷O(p, γ) ¹⁸F reaction, was analyzed. The resonance strength was about ωγ_pγ =(1.2∓0.2)×10^-6 eV, which revealed that uncertainities in thermonuclear reaction rates were reduced by orders of magnitude at nova temperatures. The uncertainty in ¹⁷O(p, α)¹⁸F reaction rates was found to be ≅30%. The results show that resonance in thermonuclear reaction reduced uncertainty in galactic synthesis of ¹⁷O, the stellar production of ¹⁸F, and oxygen isotopic ratios in nova ejecta.
