New $\alpha$ ANC measurement of the 1/2${}^{+}$ state in ${}^{17}$O at 6.356 MeV, that dominates the ${}^{13}$C($\alpha$,n)${}^{16}$O reaction rate at temperatures relevant for the s-process

Background: Accurate knowledge of the ${}^{13}$C($\alpha$,$n$)${}^{16}$O reaction cross section is important for the understanding of the s-process in AGB stars, since it is considered to b…
