摘要/Abstract

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.
