The solubility of hydrogen and of deuterium in uranium--0.222 mole fraction molybdenum alloy has been measured over the temperature range from 700 to 1350$sup 0$K with a precision of +-1 percent. The solubility displays a minimum value near 900$sup 0$K. A model, which is generally applicable to hydrogen dissolved in other metals, is presented that describes the observed phenomena, that can be extrapolated to lower temperatures, that yields the enthalpy of formation of hydrogen dissolved in the alloy at 0$sup 0$K, and that suggests a quantum mechanical treatment for interstitial diffusion.
