Heat capacities of polycrystalline nLiH and nLiD by differential scanning calorimetric method

The heat capacities of polycrystalline nLiH and nLiD were measured by differential scanning calorimeter in the temperature range from 125 to 800 K. The smoothed values of heat capacities were used to calculate various thermodynamic functions for nLiH and nLiD from 0 to 800 K. Isotopic effect on heat capacity of nLiH and nLiD is predominant at higher temperatures (>80 K) whereas below 80 K the isotopic effect is negligible.
