The interaction potentials of the He-HFDF,TF van der Waals complexes have been obtained by center of mass transformation and then employing Murrell-Sorbie potential function to fit the accurate interaction energy data, which have been computed at symmetry-adapted perturbation theory SAPT level. The close coupling calculation of the partial cross sections for collision of He with HFDF,TF is performed by employing the fitted interaction potential. This calculation is performed for incident energies from 30 meV to 120 meV, and the information of the elastic, inelastic and total partial cross sections has been obtained. Further, the change tendency and character of the partial cross sections are discussed, and the ranges of effective interaction of the beginning of elastic and inelastic scattering have been determined for He-HFDF,TFcollision system.
