Direct Measurement of the Key Ec.m.=456 keV Resonance in the Astrophysical Ne19(p,γ)Na20 Reaction and Its Relevance for Explosive Binary Systems
Abstract
We have performed a direct measurement of the ^{19}Ne(p,γ)^{20}Na reaction in inverse kinematics using a beam of radioactive ^{19}Ne. The key astrophysical resonance in the ^{19}Ne+p system has been definitely measured for the first time at E_{c.m.}=456_{-2}^{+5} keV with an associated strength of 17_{-5}^{+7} meV. The present results are in agreement with resonance strength upper limits set by previous direct measurements, as well as …
