Outline of Final Research Achievements

In this research, we aimed to observe the electron emission process of atoms by using free electron laser SACLA of RIKEN, combined use of free electron laser (FEL) and near infrared (NIR) femtosecond laser. Using X-ray beamline BL 3 at SACLA, side-band formation by NIR laser was observed in the Auger electron spectra of rare gases. The sideband intensity enables us to optimize the spatial and temporal overlap by of the two lasers. In addition, a highly-excited states of single-charged xenon was probed by using NIR laser in combination with soft X-ray beamline BL1, and their decay was probed in real time.
