A non-Gaussian distribution of 131I- ion in d.c. field resulted in two unequal values of tracer-diffusion coefficients D1 and D2 in and against the field direction, which increases with increase in intensity and duration of field application. A suitable mechanism is suggested to explain the observed results.
