| Outline of Final Research Achievements |
We proposed a new model of muon-catalyzed fusion (μCF) that involves a resonance state. We also quantitatively evaluated the contribution of in-flight μCF. For the first time, we successfully observed the X-ray spectrum emitted during the decay of the resonance state. We calculated the α-μ sticking ratio in the muon loss process in μCF and the muons released after μCF. Furthermore, we directly detected these released muons for the first time. Our theoretical calculations solved several issues that had remained unresolved for over 20 years. We proposed using the stationary high-density region formed in a gas by the interference of supersonic shock waves as the reaction field for μCF. We constructed a shock tunnel and experimentally measured the formation of the high-density region using the Schlieren method, confirming that its position, shape, and interference wavefront matched aerodynamic calculations.
