“In 1953, E. Haeffner (1) reported that after he had passed a direct electric current through a capillary tube filled with mercury, he obtained a separation of the isotopes of mercury. It was found that the heavier isotopes were enriched at the negative terminal and the lighter Isotopes at the positive terminal. This effect has since been referred to as the Haeffner Effect. Since this original experiment, other investigators have observed this effect in many other liquid and some solid metal systems.
The work of J. N. Baysden (2) showed that the separation of the isotopes in mercury could be followed by the use of mercury (203) as a radioactive tracer.
In this investigation of the Haeffner Effect in mercury a radioactive tracer, mercury (203), was used to follow the separation of the isotopes in a capillary system that did not contain an attached reservoir. The separation was followed near the cathode and near the anode by determining the change in counting rate. The change in counting ratio with time and the time necessary to reach equilibrium conditions were determined at several temperatures to determine whether these factors were temperature dependent--Abstract, page ii.
