The classical trajectory method is employed to calculate the rate coefficient k r for the reaction H + +He+He→HHe + + He at the temperatures ranging 200–350 K, based on an ab initio potential energy surface. The results show that k r is strongly dependent on the temperature, which can be well fitted by the function k r =AT Dr‐3 with A =4.192×10 −31 cm 6 /s and the reaction dimension Dr =2.706. The product molecules HHe + are found in high vibrational states.
