Study of the astrophysically important ${}^{23}\mathrm{Na}(\mathbf{\alpha },\mathbf{p}{)}^{26}\mathrm{Mg}$ and ${}^{23}\mathrm{Na}(\mathbf{\alpha },\mathbf{n}{)}^{26}\mathrm{Al}$ reactions

Abstract

The ${}^{23}$Na$(\alpha ,p{)}^{26}$Mg and ${}^{23}$Na$(\alpha ,n{)}^{26}$Al reactions are important for our understanding of the ${}^{26}$Al abundance in massive stars. The aim of this work is to report on a direct and simultaneous measurement of these astrophysically important reactions using an active target system. The reactions were investigated in inverse kinematics using ${}^4$He as the active target gas in the detector. We measured the excitation functions in the energy range of about 2 to 6 MeV in the center of mass. We have found that the cross sections of the ${}^{23}$Na$(\alpha ,p{)}^{26}$Mg and the ${}^{23}$Na$(\alpha ,n{)}^{26}$Al reactions are in good agreement with previous experiments, and with statistical model calculations.
