Study of Proton and 3He Induced Reactions on 235U at Low Energies

Highly enriched 235U targets were irradiated with 6.5−16.1 MeV protons and 20.4−42.0 MeV 3He ions. The irradiated targets were measured with γ and α spectrometric methods to identify and quantify the produced reaction products. After primary activity measurements the targets were dissolved, and interesting Pu and Np reaction products were chemically separated from the target material, and measured for activity again. From the activity results it was possible to calculate the reaction cross sections for differently produced nuclides. The data obtained from the experiment resulted in earlier unknown excitation functions on proton and 3He induced nuclear reactions on 235U.
