Abstract： Rotationally inelastic He-H2, D2, T2 collision was studied quantum-mechanically. Converged cross sections were calculated by using the close coupling method for relative kinetic energies of 0.01 to 0.54 eV. Born-Oppenheimer approximation was employed to determine the potential surface of He-D2, He-T2, and He-H2. Careful comparison between the cross sections of the isotopically substituted systems was carried out, and the regular changes of the total cross sections of the isotopically substituted He-H2 colliding systems were obtained.
