Abstract

A calculation of the exchange force between

{Li}^{+}

and He has been made with the use of simple hydrogenic state functions to represent the charge distributions of the ion and atom. The force so obtained was added to that arising from the polarizability and the van der Waals interaction between

{Li}^{+}

and He. The result was then used to calculate the mobility of

{Li}^{+}

in He gas. The theoretical value thus found, 19.4

{cm}^{2}

/sec. volt at a temperature of 18°C, is somewhat lower than the experimental one of 25.8

{cm}^{2}

/sec. volt, reported by Hoselitz.
