We present the final results of an experimental study of {mu}d and {mu}t atom scattering in solid hydrogen cooled to 3 K. Strong effects resulting from the Ramsauer-Townsend effect have been observed in the TRIUMF experiment E742 where muons were stopped in thin frozen layers of hydrogen. The measured Ramsauer-Townsend minimum energy for both {mu}d and {mu}t atoms and the minimum cross section are in agreement with theory.
