Abstract
Spectra of optical conductivity and UPS have been measured in single crystals of Fe7Se8 and Co7Se8. Experimental spectra in Fe7Se8 showed good correspondence with the DOS (density of state) spectrum obtained from the band calculation in FeSe. Magnetic properties of these crystals are discussed in connection with the electronic structures.
