An alternate approach was used to study the reactions of muonic atoms and molecules in solid layers of hydrogen isotopes. Muons stopped in a protium layer with a small admixture of tritium producing {mu}{ital p} atoms. Muon transfer from a proton to a triton generated {mu}{ital t} atoms, which were emitted into a deuterium layer. Subsequent epithermal {ital dt}{mu} molecular formation followed by {ital dt} fusion gave a prompt signal for the {mu}{ital t} emission. Fusion time spectra at various tritium concentrations were measured by detecting neutrons and {alpha} particles and the {mu}{ital p} disappearance rates were determined. The rates of {mu}{ital p}{r_arrow}{mu}{ital t} transfer and {ital pp}{mu} formation were measured to be {lambda}{sub {ital pt}}=[5.86{plus_minus}(0.10){sub {ital stat}}{plus_minus}(0.15){sub {ital syst}}({sub {minus}0}{sup +0.30}){sub {ital model}}]{times}10{sup 9} s{sup {minus}1} and {lambda}{sub {ital pp}}{sub {mu}}=[3.21 {plus_minus}(0.10){sub {ital stat}}{plus_minus}(0.14){sub {ital syst}}({sub {minus}0.06}{sup +0}){sub {ital model}(}]{times}10{sup 6} s{sup {minus}1}, respectively. Comparisons are made with the most recent theoretical values. {copyright} {ital 1996 The American Physical Society.}
