我们提出完全从头非微扰计算的积分和单微分截面的双光电离的H2的光子能量从53.9到75.7 eV。用B样条函数实现的外复标度法求解了关联初态吸收单个光子的关联连续波函数的薛定谔方程。计算结果与实验积分截面符合得很好。
We present completely ab initio nonperturbative calculations of the integral and single differential cross sections for double photoionization of H2 for photon energies from 53.9 to 75.7 eV. The method of exterior complex scaling, implemented with B-splines, is used to solve the Schrodinger equation for a correlated continuum wave function corresponding to a single photon having been absorbed by a correlated initial state. The results are in good agreement with experimental integral cross sections.
