Times Cited Count:1 Percentile:5.68(Spectroscopy)Surface carbon films on the weathered Japanese roof tiles were characterized by soft X-ray spectroscopy. From the X-ray absorption measurements, it was confirmed that the surface carbon films were oxidized by weathering. On the ohterhand, from the X-ray emission measurements, it can be confirmed that the degree of the orientation was kept in the inner carbon films.

Times Cited Count:2 Percentile:10.18(Spectroscopy)Polarized emission spectra from graphite have been measured by an EPMA and discussed by means of molecular orbital calculation of 2p electrons densities of state of graphite by some of the present authors. The present study treats the refined measurements of the polarized C K-emission band spectra from the highly oriented pyrolytic graphite (HOPG) and discusses the structure of the surface carbons of Japanese traditional smoked roof tiles, Ibushi Kawara.
