Abstract
The cross-sections for the reactions of muonium (anti-muonium)
production in the high-energy electron (positron)
scattering by nuclei
are calculated in dependence on energy and polarization of the initial
electron (positron) and polarization of the final
-meson. Since this is a coherent phenomenon the cross-sections
are proportional to
Z2. For
, due to the factor
Z2,
the cross-sections are large enough to be measured at the energies
available for the HERA Collider at DESY. The results are discussed in
connection with a test of CPT invariance.
