P. Hockett, M. Wollenhaupt, C. Lux, T. Baumert

摘要:

完整的光电离实验的可行性,其中全套的光电离矩阵元素被确定,使用多光子电离方案与偏振成形脉冲最近已被证明[Hockett et.例如,物理修订版信函112,223001(2014)]。在这里,我们扩展我们以前的工作,讨论进一步的细节的数值和分析方法,并直接比较新的断层光电子测量,这提供了一个更敏感的测试结果的有效性的结果。在这样做,我们详细讨论了光电离过程的物理,并提出了各种途径和前景,这种相干复用方法。

英文摘要:

The feasibility of complete photoionization experiments, in which the full set of photoionization matrix elements are determined, using multiphoton ionization schemes with polarization-shaped pulses has recently been demonstrated [Hockett et. al., Phys. Rev. Lett. 112, 223001 (2014)]. Here we extend on our previous work to discuss further details of the numerics and analysis methodology utilised, and compare the results directly to new tomographic photoelectron measurements, which provide a more sensitive test of the validity of the results. In so doing we discuss in detail the physics of the photoionziation process, and suggest various avenues and prospects for this coherent multiplexing methodology.
