 note = {P(論文), We measured the diffuse reflectance from 0.25 to 25μm of the Yamato-691 enstatite chondrite (E3) and compared it with that of an iron meteorite. The reflectance of Y-691 does not show any strong absorption bands except for the UV fall-off shorter than about 0.55μm in the UV-visible-near infrared wavelength region. The reflectance of Y-691 in the middle infrared wavelength region shows strong absorption bands at wavelengths longer than about 9μm mainly caused by vibrations of the Si^<4+> ion in enstatite. The reflectance of the iron meteorite (Toluca, octahedrite) does not show any strong absorption bands up to 25μm except for the UV fall-off shorter than about 0.4μm. The reflectance of the plate (polished) sample of Y-691 does not show the steep UV fall-off although that of the powder sample of Y-691 shows a relatively steep UV fall-off at wavelengths less than about 0.55μm. The plate sample of Y-691 shows a weaker UV fall-off compared with that of the iron meteorite. We can distinguish enstatite chondrite-like materials from iron meteorite-like materials on the basis of spectral features around 10μm. We may also be able to distinguish them on the basis of spectral features in the UV. We speculate that the surface composition of asteroid 16 Psyche is the enstatite chondrite-like assemblage, not the iron meteorite-like assemblage.},
