| Outline of Final Research Achievements |
The purpose of this work is to obtain Raman signal of low Z element using the resonance of metal absorption to which the low Z element is coordinated. We have tuned Ta L3 edge absorption peak of TaN compound. We found strong Raman signal. On the other hand, we have little raman signal of N when the excited X-ray is tuned to the energy less than absorption edge corresponding to non-resonant conditions. Thus we concluded Ta absorbed energy was transferred to N and N K-edge electron excited accompanied by the radiation similar to Radiative Auger process amd Multi Atom Resonant Photo Emission(MARPE). This finding is the first and never reported before. The work has clearly demonstrated to open a new in situ spectroscopy for Low Z element and also bond-specific spectroscopy. The new technique is coined to MARXR (Multiatom resonant X-ray Raman)
