| Research Abstract |
An excited state, which is a high-energy state, is formed by absorption of light(photon) in materials. The multielectron excitations, whose state means two electrons are excited by one photon, is observed in X-ray region, but the probability is very small for the elements such as Mn and Fe atoms. Recently, high-brilliant synchrotron radiation enables us to observe the phenomenon of multielectron excitations. To clarify the mechanism of multielectron excitations, a new spectrometer, a high-energy resolution X-ray emission spectrometer, was developed and a measurement of the spectra with high precision was successful. The obtained signal is not so large as expected. However, it is expected that the results play an important role to clarify the mechanism of multielectron excitations in the future.
