The close coupling approach is used to calculate the elastic and inelastic partial cross sections for collisions of helium atoms with hydrogen iodide molecules based on the intermolecular potential introduced in our previous research. The calculations are performed separately at the incident energies of 40, 75 and 100 meV. This study indicates that the excitation partial cross sections converge faster than the elastic partial cross section for each of the incident energies considered here. The excitation partial cross sections converge more rapidly for the higher excited states, and more slowly for the higher incident energies.
