## Abstract By expressing the free energy as an appropriate temperature integration over the square of the BCS energy gap function and by substituting simple but accurate analytic expressions for the latter, corresponding expressions are obtained for the specific heat in the superconducting state.
The low-temperature specific heat of a superconductor Mo 3 Sb 7 with T c = 2.2 Β± 0.05 K has been measured in magnetic fields up to 5 T. In the normal state, the electronic specific heat coefficient c n , and the Debye temperature H D are found to be 34.5(2) mJ mol Γ1 K Γ2 and 283(5) K, respectively.
We report experimental results of the electrical resistivity and the specific heat of UPd2Γ·xAia+r(nominal) single crystals. An anomaly in the specific heat, which was reported previously, has disappeared in the present measurement, although there still exists an anomaly in the thermal expansion. The
