The differential cross sections of the {sup 10}B(n, {alpha}){sup 7}Li reaction were measured at 4.17, 5.02, 5.74, and 6.52 MeV by using a gridded ionization chamber. Neutrons were produced through the D(d,n){sup 3}He reaction. The absolute neutron flux was determined through the {sup 238}U(n,f) reaction. The experiment shows that as the neutron energy increases from 4.17 to 6.52 MeV, the differential cross section changes from almost 90-deg symmetry to obviously backward peaked in the center-of-mass reference system.
