Abstract
The strengths of low-energy resonances in N-14(alpha,gamma)F-18 at 573 keV and 1136 keV have been measured using an activation method. In addition, th eir relative strength and the energy of the lower resonance have been deter mined in a prompt gamma -ray experiment. The results of these measurements are used to reevaluate the stellar reaction rate of N-14(alpha ,y)F-18. The present reaction rate at temperatures of astrophysical interest is a facto r of 2 smaller than previously reported.
