Ion transport across the gas-liquid interface in xenon

We report on investigations into the transport of positive thallium ions from gas-to-liquid and conversely liquid-to-gas, across the interface, in xenon. These studies showed that for a variety of drift field strengths and liquid depths, it was possible to transport the thallium ions from the gas phase through to the liquid. However, extraction of the positive ions from the liquid to the gas was not achieved. The difference in the two outcomes is thought to be due to the varying degrees of clustering of neutral xenon around the thallium ions in each case.
