Diffusion radius of muonic hydrogen atoms in H-D gas
The diffusion radius of the 1S muonic hydrogen atoms in gaseous H_2 targets
with various deuterium admixtures has been determined for temperatures T=30 and
300 K. The Monte Carlo calculations have been performed using the partial
differential crosssections for and atom scattering from the
molecules H, HD and D. These cross sections include hyperfine
transitions in the muonic atoms, the muon exchange between the nuclei and
, and rotational-vibrational transitions in the target molecules. The Monte
Carlo results have been used for preparing the time-projection chamber for the
high-precision measurement of the nuclear capture in the ground-state
atom, which is now underway at the Paul Scherrer Institute.Comment: 8 pages, 10 figures, 1 tabl
