• 論文の詳細を見る

• The lattice energies, infrared absorption frequencies and Debye characteristic temperatures have been calculated using a new logarithmic form A log_e(1+B/r^9) for the overlap repulsion interaction for the alkali halide crystals containing lighter ions. The potential parameters A and B have been evaluated using room temperature lattice conditions. The necessary equation for the force constant, and infrared absorption frequency have been derived. The results have been compared with the experimental data as well as with calculated values from other methods. The logarithmic form for the overlap repulsion gives better results as compared with the Born-Mayer and Pauling's potential energy functions.
