摘要
The heat capacities of polycrystalline (LiH)-Li-n and (LiD)-Li-n were measured by differential scanning calorimeter in the temperature range from 125 to 800K. The smoothed values of heat capacities were used to calculate various thermodynamic functions for (LiH)-Li-n and (LID)-L-n from 0 to 800K. Isotopic effect on heat capacity of (LiH)-Li-n and (LiD)-Li-n is predominant at higher temperatures (>80 K) whereas below 80K the isotopic effect is negligible. (C) 2010 Elsevier B.V.
