摘要：
The low-temperature lattice specific heat of very dilute FCC Al-Li alloys has been studied by applying the Green function method to an isolated substitutional Li impurity. The specific heat is very sensitive to force constant changes induced by the defect. It is observed that the contribution of the T1u mode is not preponderant. We include the effect of the second neighbours of the Li atom.
