Abstract
This first of three papers describes the preparation of sodium bromide samples on which adsorbed krypton and methane exhibit transitions in the region below one monolayer. The isotherms for these gases are reported for temperatures ranging from 64 to 85°K. The nitrogen isotherms at various temperatures show no such transition, and are discussed from the point of view of the BET theory. A device for maintaining a constant level of liquid nitrogen under reduced pressure is also described.Keywords
