• The effects of electron correlation ira FeSi are studied in teruaas of the two-band Htrbbard modelwith the density of states obtained frona the band calculation. Using the self-consistet'rt second-order perturbation theory coznbined with the local approxiunatioua, the correlation effects 011 thedensity of states and tlae optical condttctivity spectruna are investigated, and the experizmentsdone by Damascelli et al. (Physica B 230 -232 (1997) 787) are sezaaiqua??titatively reprodtrced. Itis also fotrnd that the peak at tlae gap edge is shif'ted to the lower energy region by tlue correlationeffects, as is seen in the experitner'uts.
