摘要：

This paper reports an experimental investigation of muon-catalyzed fusion in pure deuterium by detection of dd fusion neutrons. Target temperatures of 25.5150 K and gas densities of 2% and 5% liquid-hydrogen density were used. The rates F for dd formation from both hyperfine states of d atoms as well as the hyperfine transition rates were separated in a kinetic analysis of the observed time spectra. This measurement of the temperature dependence of all important rates in the dd catalysis cycle allows a comprehensive and quantitative test of the present theory of resonant molecule formation. In particular, the temperature behavior of dd formation from the d quadruplet state determines the binding energy 11=-1966.1(3) meV of the participating dd state with unique accuracy. In general, convincing agreement between experiment and theory concerning the dd formation process is found, whereas the theoretical hyperfine rates, consisting of nonresonant and resonant contributions, exceed the experimental values by 40%. © 1990 The American Physical Society.
