41 rotation energy levels / 40 radiative transitions / 210 collisional transitions for para-H2 (17 temperatures in the range 5-300K) / 210 collisional transitions for ortho-H2 (17 temperatures in the
Ab initio calculations are employed to generate the rigid rotor (RR) potential energy surface (PES) describing the interaction of the linear molecular cation HeHHe+, at its equilibrium geometry, with
Rate coefficients (in units of cm3/s) for ro-vibrational transitions between vibrational-rotational levels of para-H2 in collisions with He at different values of the translational temperature (K). H2
