| Outline of Final Research Achievements |
An electron wavefunction is a key concept to understand electronic structure in atoms or molecules and chemical reaction dynamics. The wavefunction is represented by complex and characterized by phase and amplitude distributions over position or momentum space. However, it is difficult to visualize the complex wavefunction. In our study, using an intense, infrared laser pulses (IR) and a tunable attosecond pulse train (high-harmonics, XUV), we identify the physical mechanism that the photoelectrons with magnetic quantum number m=0 can be selected from that of m=+-1. Next, we employ a two-path photoionization interference to resolve the phase distribution of photoelectrons ionized from neon gas by using the XUV and IR pulses.Using this method, we visualize the complex electron wavefunctions produced by individual ionization pathways in two-dimensional momentum space.Furthermore, we isolate an atomic phase from the spectral phase of high-harmonics.
