Findings

Total reaction cross sections were extracted for multiple isotopes.

Results facilitate better predictions of alpha-induced reaction cross sections.

Comparison of scattering data across different isotopes was enabled.

Abstract

The total reaction cross section $\sigma_{\rm{reac}}$ 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 $\sigma_{\rm{reac}}$ 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.
