论文摘要
探索了从实验室框架(LF)测量值(LFPADS)中应用基于基质的重建方案(MF)光电框架(MF)光电框架(MF)。与其他有关MF重建主题的最新作品类似,该协议利用时间分辨的LF测量值,其中通过光电离心准备和探测旋转波袋,然后进行数值重建常规。但是,与其他方法相比,本文开发的协议不需要确定光电矩阵元素,因此采用相对简单的数值形式(矩阵变换利用摩尔 - 柔性倒数)。值得注意的是,简单性允许将该方法应用于多原子分子的成功重建MFPAD。该方案在两种现实情况下以数字形式显示,$ n_2 $和$ c_2h_4 $。预计新技术通常适用于涉及多原子分子光电离的一系列MF重建问题。
The application of a matrix-based reconstruction protocol for obtaining Molecular Frame (MF) photoelectron angular distributions (MFPADs) from laboratory frame (LF) measurements (LFPADs) is explored. Similarly to other recent works on the topic of MF reconstruction, this protocol makes use of time-resolved LF measurements, in which a rotational wavepacket is prepared and probed via photoionization, followed by a numerical reconstruction routine; however, in contrast to other methodologies, the protocol developed herein does not require determination of photoionization matrix elements, and consequently takes a relatively simple numerical form (matrix transform making use of the Moore-Penrose inverse). Significantly, the simplicity allows application of the method to the successful reconstruction of MFPADs for polyatomic molecules. The scheme is demonstrated numerically for two realistic cases, $N_2$ and $C_2H_4$. The new technique is expected to be generally applicable for a range of MF reconstruction problems involving photoionization of polyatomic molecules.
