Equilibrium pressures of protium, deuterium, and tritium over lanthanum metal at atomic ratios up to 2.2 have been measured for temperatures ranging from approx. 800 K to slightly over 1000 K. The equilibrium pressures in the plateau regins increased as expected from the protide to the deuteride to the tritide. Sieverts' constants were determined at the higher temperature and decreased in this same order. Within experimental error the terminal solubilities of the three isotopes in the metal, defined by the separation of the dihydride phase from the metal, are the same.
