Abstract
Solubility measurements of H, D and T in Pd and Pd0.80Ag0.20 have been performed in a very large temperature range. A simple analytical expression is given for the equilibrium constants which describes the equilibrium between the hydrogen atoms dissolved in a metal at infinite dilution and the hydrogen molecules in the gas phase. From this expression the partial enthalpies and entropies of H, D, T in metals can easily be calculated. Also the vibrational ground state energies of H, D and T in Pd and Pd0.80Ag0.20 relative to the energy of atomic hydrogen at rest could be determined’accurately. In addition, the isotopic dependence of the phase boundaries in Pd will be discussed.
