过去十年，在完全运动学解析的原子电子轰击电离领域及其密切相关的双光电离领域取得了非凡的理论进展。由于与涉及长程库仑势的破裂问题相关的形式和计算困难，这些过程的计算具有挑战性。然而，目前，无论考虑的运动学或探测器的几何形状如何，都可以针对原子氢和氦等简单目标准确计算这些过程。我们报告计算进展，以及它如何导致对库仑少体问题的形式主义的更深入理解。
The past decade has seen extraordinary theoretical progress in the field of fully kinematically resolved atomic electron-impact ionisation, and its closely related field of double photoionisation. These processes were challenging to calculate due to formal and computational difficulties associated with break-up problems involving the long-range Coulomb potential. Presently, however, these processes can be calculated accurately for simple targets such as atomic hydrogen and helium, irrespective of the kinematics considered or the geometry of detectors. We report on the computational progress, and how it has resulted in a deeper understanding of the formalism of Coulomb few-body problems.
