摘要: The vibration spectra and specific heats of three body-centred cubic transition metals, α-iron, tungsten molybdenum have been calculated fromBhatia’s model electron-lattice interaction by considering second neighbour inter-ionic interactions. force constants are determined from the experimental elastic one measured frequency. compared with available data computing equivalent Debye temperature as a function agreement experiment is reasonably satisfactory.
