Outline of Final Research Achievements |
The main purpose of this study was focusing on the many-body effect of iron Hem and discussing electronic states of the hem protein from a viewpoint of solid states physics. In this research, we first constructed a porphyrin cluster model. Next, we succeeded in computing x-ray core-level spectra of resonance soft X-ray emission spectroscopy, X-ray photoelectron spectroscopy and X-ray absorption spectroscopy based on the theoretical model. Last year that was the final year was planned to compare with the experimental spectrum, but the experimental progress was delayed. Therefore a direct comparison between experimental spectrum and theoretical calculation became impossible. Therefore, we changed the original plane. We examined how the electronic state changes as a function of the physical parameters.
We have also studied chromium oxide NaCr2O4 which has almost the same state as heme iron electronic state. This result was published in Physical Review B in January 2018.
