Low energy cross-sections measurement of D-D and D-T reactions

The cross sections of deutron-deutron reaction for deutron energy from 15 KeV to 150 KeV and of deutron-tritium reaction for deutron energy from 13.8 KeV to 114.3 KeV were measured by the process of passing a deutron and tritium beam into a gas target formed by a differential pumping system and two capillary pipes. Experiments in two steps-angular distribution measurement and absolute differential cross-section measure ment-were performed at 3 Cockcroft-Walton generators with terminal voltages of 50 kV, 150 kV and 300 kV. Emperical fit of D-D reaction data to Gamow formulae and comparison of D-T reaction data with BWE theory were given
