Abstract: | This paper presents the final results of an experimental study of the kinetics of the muon catalysed
fusion (MCF) in solid hydrogen-deuterium mixtures (H/D) at a temperature of 3 K.
The experiment E742 was carried out on a TRIUMF meson facility in Canada.
Four exposures were performed at different deuterium concentrations in the H/D mixture:
cd = 0.0005, 0.02, 0.15 and 0.75.
A simultaneous analysis of the measured time distributions of the 5.5 MeV γ-quanta and the 5.3 MeV
conversion muons obtained from nuclear fusion in the pdμ molecule allowed to extract the
values of MCF chain parameters in the H/D mixture: the fusion partial
rates for different nuclear spin states of the pdμ molecule, and
the pdμ molecule formation rate. The experimental data fitting procedure was conducted
in two ways: using solely the analytical formulae describing the kinetics of
the MCF processes in the H/D mixture, and the detailed Monte Carlo simulation of the entire
experiment.
The results obtained by these two methods are consistent with each other and confirm
the existence of the Wolfenstein-Gerstein effect. |
