Neutron spectroscopy of ${}^{26}$Mg states: constraining the stellar neutron source ${}^{22}$Ne($\alpha ,n$)${}^{25}$Mg

C. Massimi, The n_TOF Collaboration

This work reports on accurate, high-resolution measurements of the ${}^{25}$Mg($n,\gamma$)${}^{26}$Mg and ${}^{25}$Mg($n,tot$) cross sections in the neutron energy range from thermal to abo…
