Total reaction cross sections from elastic alpha-nucleus scattering angular distributions around the Coulomb barrier

Abstract

The total reaction cross section ${\sigma }_{\mathrm{reac}}$ is a valuable measure for the prediction of $\alpha$-induced reaction cross sections within the statistical model and for the comparison of scattering of tightly bound projectiles to weakly bound and exotic projectiles. Here we provide the total reaction cross sections ${\sigma }_{\mathrm{reac}}$ derived from our previously published angular distributions of $\alpha$-elastic scattering on ${}^{89}$Y, ${}^{92}$Mo, ${}^{112,124}$Sn, and ${}^{144}$Sm at energies around the Coulomb barrier.
