概要

• 論文の詳細を見る

• The vibrational spectrum of lithium and its specific heat are calculated using Bhatia's three force constant model for monovalent metals. The calculations are made with two sets of elastic constants, one with those measured at 78℃ K and the other with Fuchs' calculated values at absolute zero. The calculated specific heat and the values of Debye characteristic temperature are compared with the experimental data. It is found that the calculations based on the elastic data at 78℃ K give better agreement at higher temperatures while those from elastic constants at absolute zero agree better at lower temperatures.
