Title: Stability of the lanthanide hydrides

Abstract

A review of the unclassified literature is presented that tabulates the reported equilibrium pressure data of the lanthanide diprotides and dideuterides in the form log P(torr) = A/T + B. Values of the thermodynamic properties are tabulated and the trend in those data is explained by several semiempirical formulas. The isotope shifts are calculated by two independent means. For any lanthanide metal, the heat of formation of the dihydride is about 1.5 kcal/mole more negative than the dideuteride, which, in turn, is about 0.5 kcal/mole more negative than the ditritide. These values agree well with the experimental values. 4 figures, 2 tables.
