Abstract

For the first time, we have observed the 6.76 keV radiative transition photons associated with the μ^- transfer process from (tμ^-) atoms to ³He nuclei through intermediate (t³He μ^-) mesomolecule formation in a solid T₂ target. The radiative decay branching ratio of the (t³He μ^-) mesomolecule and the muon transfer rate were determined and compared with theoretical values. We also studied an accumulation process of ³He atoms in a solid T₂ target by observing the neutron decay rates originating from t-t muon-catalyzed fusions. Their time dependence indicates a sudden ³He bubble formation in the solid T₂ at an atomic concentration of 130 ppm.
