Abstract
We observed the dependence of the rate of the muon-catalyzed fusion (μCF) on the ortho–para state (the nuclear spin state) of deuterium in order to investigate the source of the surprising contradiction of the resonant formation rate of a ddμ molecule in solid between experiments and theories. The ortho–para dependence of the molecular formation rate and the dμ hyperfine transition rate was clearly observed for the first time. The rate of the hyperfine transition by scattering was determined and was smaller than that of the theoretical prediction. The back decay rate was experimentally determined for the first time. Also, new insight for phenomena of the dd–μCF in solid was presented by interpreting the observed ortho–para dependence.
