Abstract

Results are reported for the utilization of sodium, sodium halides, and lithium chloride on rhenium and on oxygenated rhenium surfaces. The oxidation of a rhenium surface was found to cause an increase in its work function. As a result the ionization efficiencies for sodium and sodium halides incident on this surface are increased from about 0.20 to unity. The efficiency for lithium chloride is also increased to a value probably close to unity. The oxide layer which is formed even at low air pressures (5×10-7 torr) seems to be stable only up to about 1650°K.
