Abstract
Low-temperature specific heat of high-purity calcium has been measured with an adiabatic calorimeter with a mechanical heat switch to avoid helium exchange gas errors, over the temperature range 1.1–4.2 K. The values obtained for the electronic coefficient of specific heat γ and the Debye temperature θD are γ=1.99±0.05 mJ/moleK 2 and θD=250±4K.
