New recommended ωγ for the Er c. m. =458 keV resonance in Ne 22 (p,γ) Na 23

Journal Article (Journal Article)

The Erc.m.=458 keV resonance in Ne22(p,γ)Na23 is an ideal reference resonance for measurements of cross sections and resonance strengths in noble gas targets. We report on a new measurement of the strength of this resonance. Data analysis employed the TFractionFitter class of root combined with geant simulations of potential decay cascades from this resonance. This approach allowed us to extract precise primary branching ratios for decays from the resonant state, including a new primary branch to the 7082-keV state in Na23. Our new resonance strength of ωγ(458 keV) = 0.583(43) eV is more than 1σ higher than a recent high-precision result that relied on literature branching ratios.
