| Outline of Final Research Achievements |
A time-resolved imaging spectroscopy technique has been developed, which simultaneously realizes time-resolved soft X-ray spectroscopy and two-dimensional spatial imaging. Two-dimensional spatial distribution of soft X-ray absorption spectra is obtained without scanning the monochromator, by illuminating the sample with wavelength-dispersed X rays and measuring two-dimensional intensity distribution of emitted electrons with a photoelectron emission microscope. The technique was applied to a Pt/Co/Pt thin film, which had been irradiated by a laser in the air, and it was found that the spectra for inside and outside of the laser spot are different. The feasibility of the technique has been thus confirmed.
