Abstract
It is shown that, for s.v.p, in the range 1–100 mm Hg, evaporation (condensation) of alkali metals goes via liberation (absorption) of both monatomic and diatomic molecules by the liquid surface. In this pressure range, dimerization (dissociation) occurs as the result of a chemical reaction at the liquid surface, and the coefficients of condensation of monatomic and diatomic molecules are close to unity.
