摘　　要：本文在walecka介子-核子模型的基础上,在核物质中第一次研究了四级交换图对核子自能的虚部以及相对论微观光学势和Schrodinger等效势的贡献。The contribution of the fourth order exchange diagrams is first studied to the imaginary part of nucleon self-energy, the relativistic microscopic optical potential and the Schrodinger equivalent potential of the relativistic microscopic optical potential based on Walecka's meson-nucleon model.

关 键 词：光学势 四级交换图 等效势 自能
