我们报告了一个有效的实现的空间两区方法数值求解薛定谔方程，使用一个典型的基组分解，并将其应用到双电子波函数的双多光子电离的研究。我们对这个知之甚少的过程进行了电子相关度随时间变化的首次计算。我们的研究结果显示了一个特别敏感的窗口的强度正好与众所周知的“膝盖”制度的离子计数数据。
We report an efficient implementation of a spatial two-zone method for solving Schrodinger’s equation numerically, using a canonical basis set decomposition, and also its application to two-electron wave functions in a study of double multiphoton ionization. We make the first calculation of the time-dependent degree of electron correlation for this poorly understood process. Our results show a particularly sensitive window of intensities coinciding exactly with the well-known “knee” regime in ion-count data.
