Low-Temperature Specific Heat of Antimony

Abstract

The specific heat of antimony has been measured from 0.54 to 4.0\ifmmode^\circ\else\textdegree\fi{}K. A least-squares fit to the data in the 0.54 to 1.1\ifmmode^\circ\else\textdegree\fi{}K range gave $C=(0.105\ifmmode\pm\else\textpm\fi{}0.002)T+(0.210\ifmmode\pm\else\textpm\fi{}0.002){T}^{3}+(0.0048\ifmmode\pm\else\textpm\fi{}0.0004){T}^{\ensuremath{-}2}$ mJ/mole \ifmmode^\circ\else\textdegree\fi{}K and a Debye temperature of 210.0\ifmmode\pm\else\textpm\fi{}0.7\ifmmode^\circ\else\textdegree\fi{}K. The uncertainties are rms deviations of the means. These results are in good agreement with specific-heat, Fermi-surface, and quadrupole-resonance data. Thermometer calibration in the ${\mathrm{He}}^{3}$ range is discussed.
