摘要: Close coupling calculations have been carried out for rotational excitations in He-H2 collisions with symmetric isotopic substitution (He-H2, D2, T2) and asymmetric isotopic substitution (He-HD, HT, DT). Cross sections have been obtained at the incidence energy of 0.3eV. Based on the calculations, the effect of isotopic substitution on atom-diatom collisions is discussed.
