Abstract
Cross sections and forward/backward ratios in the laboratory reference system were measured for 143Nd(n, )140Ce reaction at 4.0, 5.0 and 6.0 MeV and for 147Sm(n, )144Nd reaction at 5.0 and 6.0 MeV. A twin-gridded ionization chamber and large area back-to-back 143Nd2O3 samples and 147Sm2O3 samples were employed. Experiments were performed at the 4.5 MV Van de Graaff of Peking University, China. Fast neutrons were produced through the D(d, n)3He reaction by using a deuterium gas target. A small 238U fission chamber was employed for absolute neutron flux determination and a BF3 long counter was used as neutron flux monitor. Present experimental data are compared with previous measurements, evaluations, and model calculations.
