Abstract: | This paper reports on an experiment for testing natural nuclear fusion
at low temperature searching for evidence of the origin of $^{3}$He from
natural nuclear fusion in deep Earth. The experiment was carried out
using deuterium-loaded titanium foil samples and powder sample.
Detection of charged particle was carried out using a low-level
charged particle spectrometer. An Al foil was used as an energy
absorber for identification of charged particle. Although the
counting rate is very low in the experiment, the emission of
energetic particle from the sample is observed and the particle is
identified as a proton having energy about 2.8\,MeV after exiting the
titanium sample. This work provides a positive result for the emission of
charged particle in the deuterium-loaded titanium foil samples at
low temperature, but a negative result for the deuterium-loaded
titanium powder sample. The average reaction yield is deduced to be
(0.46$\pm $0.08) protons/h for the foil samples. With the suggestion
that the
proton originates from d--d reaction, we calculate the reaction rate
for d--d reaction, and the obtained result is 1.4$\times $10$^{ - 24}$
fusion/d--d$\cdot $sec. The negative result of the deuterium-loaded
titanium powder sample suggests that the reaction yield might be
correlated with the density or microscopic variables of
deuterium-loaded titanium materials. The negative result also
indicates that d--d reaction catalysed by $\mu $-meson from cosmic
ray can be excluded in the samples in this experiment. |
