The migration of the isotopes in a Hall field at 343K was investigated by using resistometric and tracer methods (table 125). It was found that all of the isotopes migrated towards the negative Hall electrode. The effective charges for migration in the Hall field were 194e in the case of H, and 464e in the case of D and T.
