Popis:	General analytical expressions for the transport collision integrals ${\ensuremath{\Omega}}^{(l,s)}(T)$ for binary collisions of atoms that can interact through many different (repulsive-attractive as well as repulsive) potentials are derived. The integrals allow one to calculate the transport coefficients (viscosity, thermal conductivity, and ordinary and thermal diffusion coefficients) in gases dominated by collision systems driven by poorly understood multiple-force interactions. The approach is used to calculate the transport integrals for several collision systems, and the results are compared with the detailed ab initio calculations available for some well understood open-shell systems.
