论文摘要
我们研究了与相对论光电子相对应的大型光子能量的$ s $状态在受足够弱的中央场$ v（r）$限制的系统中的光电离世。我们证明，可以在不求解波方程的情况下获得光电离截面的能量依赖性。我们表明，横截面的能量依赖性的形状取决于结合电位$ V（r）$的分析性能。我们发现电势V（r）$的横截面，这些$ V（r）$在实际轴和复杂平面上具有奇异性。
We study the photoionization of the $s$ states in the systems bound by sufficiently weak central fields $V(r)$ for the large photon energies corresponding to the relativistic photoelectrons. We demonstrate that the energy dependence of the photoionization cross section can be obtained without solving the wave equation. We show that the shape of the energy dependence of the cross section is determined by analytical properties of the binding potential $V(r)$. We find the cross sections for the potentials $V(r)$ which have singularities in the origin, on the real axis and in the complex plane.
