从同一种Skyrme相互作用出发,利用Green函数的质量算符方法,推导了氘-核微观光学势的解析公式;利用半经典变分方法,确定了靶核的核子密度分布。然后,再利用上述计算公式和密度分布,系统地研究了在不同的氘核入射能量下2D+40Ca,2D+60Zr和2D+208Pb的光学势实部和虚部。这样得到的氘-核光学势是完全自洽和微观的。The analytical formula for deuteron-nucleus microscopic optical potentials is derived using the mass operator method of Green function, and the nucleon density distributions of target nuclei are determined with the semiclassical variation (SCV) approach. These formula and density distributions are utilized ro evaluate the real and imaginary parts of 2D+40Ca,2D+60Zr and 2D+208Pb optical potentials at different energies. The potentials obtained in this way are fully selfconsistent and microscopic, since the same Skyrme interaction is employed in determining the nucleon density distributions of target nuclei and in clacula-ting the potentials.
