Measurement of cross sections for the 147Sm(n, α) 144Nd reaction at 5.0 and 6.0 MeV

Measurement of cross sections for the 147Sm(n, α) 144Nd reaction at 5.0 and 6.0 MeV

Cross sections of the 147Sm(n, α) 144Nd reaction were measured at En=5.0 and 6.0 MeV. A twin gridded ionization chamber was used as a charged particle detector and two large area 147Sm 2O 3 samples placed back to back were employed. Experiments were performed at the 4.5 MV Van de Graaff accelerator...

Zusammenfassung:Cross sections of the 147Sm(n, α) 144Nd reaction were measured at En=5.0 and 6.0 MeV. A twin gridded ionization chamber was used as a charged particle detector and two large area 147Sm 2O 3 samples placed back to back were employed. Experiments were performed at the 4.5 MV Van de Graaff accelerator of Peking University. Neutrons were produced through the D(d, n) 3He reaction with a deuterium gas target. Absolute neutron flux was determined by a small 238U fission chamber. Present cross-section data are compared with existing results of evaluations and measurements.
