Description

A novel method for extracting absolute resonance strengths has been investigated. By implanting 22Ne ions into a thick aluminum backing and simultaneously measuring the 22Ne+p and 27Al+p reactions, the strength of the Erlab=479 keV resonance in 22Ne(p,γ)23Na was determined to be ωγ=0.524(51) eV. This result has significantly reduced uncertainties compared to earlier work. Our results are important for the absolute normalizations of resonance strengths in the 22Ne(p,γ)23Na hydrogen-burning reaction and in the 22Ne+α s-process neutron-source reactions.
