摘要：
Total and transport cross-sections for the elastic collisions between excited (a mu)(n) or (a pi)(n) atom (a = p,d,t) and hydrogen atom are calculated in the energy range 0.01 eV less than or equal to E less than or equal to 30 eV and the principal quantum number values n=2-10 using the quantum mechanical approach developed earlier. The theory predicts a strong isotope effect and nontrivial dependence on the negative particle mass, especially for energy E less than or equal to 0.4 eV.
