In this thesis, we establish a new approach in muon catalyzed fusion
studies, the time-of-flight method with an atomic beam of muonic tritium,
and report results for muonic tritium scattering and epithermal
*dµt*
resonant formation, providing the first quantitatve
measurements on these reactions.

Emission of muonic tritium from a solid hydrogen thin film into vacuum was
observed via imaging of muon decay electrons, and the measurement of the
position and the time of muon decay provided spectroscopic evidence for
the Ramsauer-Townsend effect in the *µt* + *p*
interaction. The RT minimum
energy was determined to be
eV, in fair agreement with
quantum three body calculations.

Using this *µt*
beam, we have confirmed theoretical *µt* + *d*
scattering cross sections to an accuracy of 10% by measuring the
attenuation of *µt*
through a deuterium layer. The importance of
*p*-wave scattering in the *µt* + *d*
interaction, as suggested by the
theory, was also confirmed by our data via comparisons with Monte Carlo
calculations assuming different scattering angular distributions.

The existence of a predicted resonance for *dµt*
formation in *µt* + D_{2}
collisions was directly confirmed for the first time.
Our results correspond to a peak resonance rate of
s^{-1} in Faifman's model, more than an order of magnitude larger
than the room temperature rates, and indicate a resonance energy of
eV for the F=1 resonance peak in ortho deuterium.

Assuming the theoretical [(*dµt*)*dee*]
energy spectrum,
these results imply sensitivity to the binding energy of the loosely bound
state of the *dµt*
molecule, with an accuracy approaching the
magnitude of the relativistic and QED effects.
