Heat Capacity of Palladium below 4.2°K

Heat capacity measurements below 4.2^∘{}K have been made on extremely pure palladium. The resulting values of electronic heat capacity and Debye temperature differ from previous work, it being found that γ=(9.87±0.11)×10^-3 joule mole^-1 deg^-2 and θ=299±12^∘K. The effects of changes in the physical and chemical state of the specimen have been investigated with a view to understanding the discrepancies between the various determinations of the low-temperature atomic heat of palladium.
