First direct limit on the 334 keV resonance strength in the ${}^{22}$Ne(α,γ)${}^{26}$Mg reaction

D. Piatti, E. Masha, M. Aliotta +44

In stars, the fusion of ${}^{22}$Ne and ${}^4$He may produce either ${}^{25}$Mg, with the emission of a neutron, or ${}^{26}$Mg and a $\gamma$ ray. At high temperature, the ($\alpha ,n$) channel domi…
