Study of the reactions H2+ + He→HeH++H and HeH+ + H→H2++He using crossed beam techniques

摘要: The proton transfer reactions H2+ + He→HeH++H and HeH+ H→H2++He have been studied in the laboratory energy range 1–25 eV. first process, which is endothermic for ground state reactants, has over indicated with different degrees of vibrational excitation present particles. Below 9 eV, reaction found to depend strongly on while above this cross sections appear mainly kinetic reactants. exothermic reverse exhibits a 1 / ν dependence low‐energy region indicating an ion‐dipole mechanism. Methods measuring degree dissociation obtained forming hydrogen atom beam are discussed.
