Deuterated liquid scintillator (NE230) as a fast neutron detector for cold-fusion and other research

Deuterated scintillators (NE230) can provide, without time-of-flight, usable neutron energy spectra for neutrons E/sub n/>or=1 MeV. The authors have assembled and calibrated several of these detectors and used them in experiments searching for d+d fusion-neutron emission (E/sub n/, 2.5 MeV) in Pd+D/sub 2/O electrolysis and Ti+D/sub 2/ adsorption at LN temperatures. The detectors yielded direct fusion-neutron spectra and set limits in the Pd+D and Ti+D experiments of <7*10/sup -24/ fusion n/s/dd pair and <3*10/sup -24/ fusion n/s/dd pair respectively. In addition, these detectors have been used for in-beam accelerator experiments requiring coincidence between fast neutrons and scattered ions.<
