The energy of the first level above the proton threshold in ${}_{}{}^{18}{}_{}{}^{}\mathrm{F}$ has been determined to be 5672.57±0.32 keV by γ-ray measurements using the ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$(α,γ${)}^{18}$F reaction. The change in the excitation energy of this level previously measured at 5668±2 keV affects significantly the calculated reaction rate for ${}_{}{}^{17}{}_{}{}^{}\mathrm{O}$ destruction during hydrogen burning in stars.
