SOME PROPERTIES OF SOLID HYDROGEN AT SMALL MOLAR VOLUMES

摘要

Apparatus and experimental procedures are described for the measurements of properties of solid hydrogen over the volume range from 15 cc/M to 23 cc/M and the temperature range from 1.3 °K to 20 °K.nThe lattice heat capacity of hydrogen was measured at constant pressure, and at 22.56, 19.83, and 18.73 cc/M. The results are com¬pared with simple theories, and with the lattice properties of other solids. Some thermodynamic properties of solid hydrogen are de¬duced from the heat-capacity measurements.
