论文摘要
我们提出了一种从通过强激光场电离的光电子动量分布中检索原子或分子中单活性电子电位的方法。在这种方法中，由于旨在重现给定动量分布的优化程序，在某些限制内的电位变化。使用时间依赖性的schrodinger方程的数值解进行电离的优化，用于模型一维原子的电离显示了潜在重建方法的良好精度。这适用于用于表示重建下电势的不同方式，包括通过在空间网格上指定其值来确定电位的参数化和确定。
We present a method for retrieving of single-active electron potential in an atom or molecule from a given momentum distribution of photoelectrons ionized by a strong laser field. In this method the potential varying within certain limits is found as the result of the optimization procedure aimed at reproducing the given momentum distribution. The optimization using numerical solution of the time-dependent Schrodinger equation for ionization of a model one-dimensional atom shows the good accuracy of the potential reconstruction method. This applies to different ways used for representing of the potential under reconstruction, including a parametrization and determination of the potential by specifying its values on a spatial grid.
