Description
The absolute strengths of the39K(p,γ)40Ca resonances at Esub(p) = 1130, 1344, and 2043 keV have been determined to be Ssub(cm) = 1.6 +- 0.2, 4.1 +- 0.5 and 14.3 +- 1.3 eV, respectively. Relative strengths were measured for resonances in the range 0.7 < Esub(p) < 2.9 MeV. The astrophysical reaction rates of hydrogen burning of 39K in explosive oxygen burning in the stellar temperature region of T = (1.0-7.0) x 109 K are compared with Hauser-Feshbach calculations. The effect of the revised reaction rates on the 39K abundance is discussed. (auth)
