Abstract
IN the design of experiments to separate isotopes by means of thermal diffusion, as for example by the highly successful continuously convective method devised by Clusius and Dickel1, much depends on the value of α, defined by α = kT/c1c2, where c1 and c2 are the volume-fractions of the constituents 1 and 2 (so that c1 + c2 =; 1), and kT is the thermal diffusion ratio; α, which may be called the thermal diffusion factor, determines the magnitude, and its sign determines the direction, of the thermal diffusion.
