概要

• 論文の詳細を見る

• The Grtneisen parameters of alkali metals (Li, Na, K & Rb) have been computed atvarious temperatures from the experimental and the recent theoretical values of thepressure dependence of the elastic constants, using an improved CGW model for theirlattice dynamics. The computation is carried out by a modified Houston's method inwhich the integral is evaluated by a six term approximation. The Grfineisen parameterscalculated in our present study show reasonably satisfactory agreement with experim-ental observations.
