摘要The close-coupling method is utilized to calculate partial cross sections for elastic and inelastic scattering of He atoms with HX (X=F, Cl, Br) molecule based on the CCSD (T) potential energy surfaces obtained in the previous research. The calculation is performed at the incident energy of 200meV. The rationality of our results has been confirmed by comparison with the available theoretical results. The tendency of the elastic and inelastic rotational excitation partial wave cross sections varying with the reduced mass of the three systems is obtained.
