Measured cross-section data of the 10B(n,α1)7 Li reaction in the energy region from 0.1 to 2.0 MeV are treated by a renormalization procedure. Renormalization constants are applied to results of seven different experiments, keeping their energy-dependent shapes unaltered. The procedure provides quantitative arguments to reject some discrepant results, and it yields recommended values that are lower than the cross-section values of the ENDF/B-IV file.
