Abstract :
A spallation neutron source consisting of an extended lead target surrounded with a paraffin moderator irradiated by 1, 1.5, and 2.0 GeV protons is used to study neutron capture and transmutation reaction rates in 139La, 129I and 237Np samples in secondary neutron fluences. Reaction rates are obtained by activation analysis using HPGe detectors. The results are compared with calculations using a cascade-evaporation model.
