Abstract

A theoretical study of the low field mobility of

{He}_{2}^{+}

in its parent gas is described. Forces between

{He}_{2}^{+}

and He are calculated by means of perturbation theory. Determination of the scattering phase shifts then yields the momentum transfer cross section as a function of collision energy. Use of the Chapman-Enskog theory of diffusion permits the calculation of the mobility as a function of temperature.
