Atomic Heats of Copper, Silver, and Gold from 1°K to 5°K

摘要: The atomic heats of copper, silver and gold have been determined in the temperature interval 1.0\ifmmode^\circ\else\textdegree\fi{} to 5.0\ifmmode^\circ\else\textdegree\fi{} K. measured values can be described adequately by a linear plus cubic term temperature. Any deviations from this relationship are explainable terms inaccuracies presently accepted helium vapor pressure\char22{}temperature scale. In fact, it is shown that scale corrections, necessary correct data simple law given above, essentially agree with corrections suggested other work. Values coefficient (electron heat capacity) Debye characteristic derived compared several indirect determinations, as well calorimetric data, where possible. electronic capacity work consistently lower than those previous on copper silver.
