分子框架光电子角分布（MFPAD）和反冲碎片相对于电子发射方向的角分布的一般表达式，称为“电子框架光离子角分布”（EFPAD），分析内的偶极近似。我们描述的投影方法作为一种工具，以提取最大量的信息MFPAD和EFPAD记录的光电子-光离子符合动量谱，使用N 1 s光电离NO在412 eV作为一个具体的例子。通过模拟的实验EFPAD与电子检测只有两个方向，我们证明了EFPAD的有用性，以及如何获得完整的信息EFPAD和MFPAD从这样一个有限的测量EFPAD。
General expressions for molecular frame photoelectron angular distributions (MFPAD) and the angular distributions of the recoil fragments relative to the electron emission direction, called ‘the electron frame photoion angular distribution’ (EFPAD), are analysed within the dipole approximation. We describe the projection methods as a tool to extract the maximum amount of information about MFPAD and EFPAD recorded by photoelectron–photoion coincidence momentum spectroscopy, using the N 1s photoionization of NO at 412 eV as a specific example. Via a simulation of an experiment on EFPAD with electron detection in only two directions, we demonstrate the usefulness of the EFPAD and how to obtain full information on the EFPAD and MFPAD from such a restricted measurement of the EFPAD.
