摘要：

Cross sections and thermal rate coefficients for rotational and vibration excitation of the four stable isotopologues of the 4HeH+ ion by electron impact are presented. The data are calculated using a previously developed theoretical approach. The obtained rate coefficients are fitted to analytical formulas with the 10-10,000 K interval of applicability. These present results could be useful in tokamak plasma and astrophysical modeling and can help in the detection of these species in the interstellar medium.
