Heat Capacity of Tungsten between 4 and 15°K

The heat capacity of tungsten was determined in the temperature range 4 to 15^∘{}K. The results obtained can be represented by the equation: C(joules/moledeg)=1.11×10^-3T+1943(T/378)³, with an average deviation of about one percent. The electronic specific heat coefficient and the Debye θ are evaluated to be (1.1±{}0.1)×{}10^-3 joules/mole deg² and 378±{}7^∘{}K, respectively. The results are compared with the theoretical calculations of Fine and of Manning and Chodorow and with measurements by other investigators in neighboring temperature ranges.
