Measurement of the temperature dependence of the dd μ molecule formation rate in dense deuterium at temperatures of 85–790 K

Muon catalyzed fusion (MCF) in deuterium was studied by the MCF collaboration on the Joint Institute for Nuclear Research Phasotron. The measurements were carried out with a high-pressure deuterium target in the temperature range 85–790 K at densities of about 0.5 and 0.8 of the liquid hydrogen density. The first experimental results for the ddμ molecule formation rate λ ddμ in the temperature range 400–790 K with a deuterium density of about 0.5 of the liquid hydrogen density are presented.
