and helium gas mixtures

A new set of swarm data in 
and helium were experimentally determined by the pulsed Townsend method over the range 
Td (1 Td 
V 
): the effective ionization coefficient 
, the drift velocity 
and the longitudinal diffusion coefficient 
. The limiting 
values of -He gas mixtures were derived from the experiment and found to vary linearly with the concentration in the mixtures.
