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 139 La, 129 I and 237 Np 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.
