Abstract

The explosive burning of 17O, which exhibits resonance at E Rlab = 190 keV in the 17O(p, γ) 18F reaction, was analyzed. The resonance strength was about ωγ =(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.
