fermi dirac statistics

On the basis of Green function theory and Fermi Dirac approximation,and having considered the temperature dependence of nucleon chemical potential,the imaginarypart of optical potential is analytically calculated.

在格林函数理论和费米－狄拉克近似的基础上，考虑到核子化学势的温度依赖性，解析地计算了热核物质中光学势虚部，并给出了核子化学势的解析公式。
