Abstract

For the first time, we observed the dependence of the [Formula presented] formation rate and the [Formula presented] hyperfine-transition rate on the ortho-para state in muon-catalyzed fusion in the solid [Formula presented] state, and found that the effect is even opposite to a recent theoretical prediction. We also determined the back-decay rate and the hyperfine-transition rate via scattering in solid state by using the ortho-para dependence. A theory to describe properly our experimental result is called for to understand the nature of muon-catalyzed fusion in the solid state.
