Abstract:
An investigation is made of the deuterium-deuterium nuclear fusion in a gas-pressurized, thermally cycled titanium-deuteride in the temperature region between 80 and 600 K. A compound neutron and, detection system, consisting of 30 BF 3 proportional counters, 2 Nal(Tl) scintillators and an NE213 scintillator, all housed in a neutron moderator, together with 4 separate long counters, was designed to search for random emission of fusion neutrons from the deuteride, as well as burstcorrelated neutron emission in the < 1 ms region, during thermal cycles. No significant emission of any of the products associable with deuterium-deuterium fusion was observed during any of the 21 experiments performed with two different deuterides, having D /Ti ratios of 1.003 ± 0.018 and 0.428 ± 0.008. An upper limit for the rate of nuclear fusion of deuterium for a duration between ~1 min and ~4 h was found to be 5 x 10-24 dd-1 s-1.
