Search for Nuclear Products of The D+D Nuclear Fusion

抄録

Nuclear products which were caused by the D D nuclear fusion reactionwere searched in electrolytic cells and in gas phase of Pd D systems.Measurements of nuclear products were made for gamma-ray, neutron, tritiumand helium. To detect neutron, liquid scintillation and ³He counters wereused. For gamma-ray measurement, a NaI detector was used. For tritiumconcentration measurement in gas phase, a gas proportional chamber was fabricated and operated in low background level. The signals of those detectorswere fed to Pulse Height Analyzer and recorded as energy spectra which werecarefully compared with background spectra. Different type of neutron hunting was also tried in the instants of pressurizing and depressurizing the deuteriumgas in crystal. A large size crystal of tungsten bronze was prepared forthe experiment.
