Cross sections and forward/backward ratios for the {sup 143}Nd(n,{alpha}){sup 140}Ce reaction were measured at E{sub n} = 4.0, 5.0 and 6.0 MeV using a twin-gridded ionization chamber and two large area back-to-back {sup 143}Nd{sub 2}O{sub 3} samples. Experiments were performed at the 4.5 MV Van de Graaff of Peking University, China. Fast neutrons were produced through the D(d,n){sup 3}He reaction by using a deuterium gas target. A small {sup 238}U fission chamber was employed for absolute neutron flux determination and a BF3 long counter was as a neutron flux monitor. Present experimental data are compared with previous measurements, evaluations, and model calculations.
