摘要：

The ratio D//T/ mu between the transverse diffusion coefficient and the mobility has been measured for Li** plus ions in He at 295 K and for 5 less than equivalent to E/n//0 less than equivalent to 200 Td, using a modified Townsend slit-type apparatus. A comparison of the experimental results with theoretically calculated D//T/ mu values indicates that Li** plus -He interaction potentials V(r) found from analysis of mobility data are too soft in the repulsive region.
