Description

The Ec.m. = 536 keV and Ec.m. = 542 keV resonances in the 15N(α,γ)19F reaction have been studied using a thick Ti15N target, determining ωγ = (9.7±2.0)x10-5 eV and ωγ<1x10-5 eV for these two resonances, respectively. For the 542 keV resonance this value is substantially smaller than had been assumed in earlier model calculations, and this reduces the rate of the analog 15O(α,γ)19Ne reaction (connecting the Hot CNO cycle and the rp-process) by a factor of ≅ 3 for temperatures in the region of T9=1.
