| Abstract: | Based on the improved atomic model with considering temperature and density, the density distribution of the free electrons is dealt with by partial wave method based on the central field approximation. By an average of approximate treatment, the energy band split is given. In the atomic structure of the self-consistent calculation the band overlap is used as the free electron dynamic criterion. Electronic pressure, energy, heat capacity and other thermodynamic factors of gold are calculated |
