Circularly polarized x rays from a synchrotron light source were used in photoemission from thin fcc Fe films on Cu(100). The measured exchange splitting for the 3[ital s] and 2[ital p] levels in these films is reduced from that measured in bulk bcc Fe. For both the 2[ital p][sub 3/2] and the 2[ital p][sub 1/2] levels the splittings are about half that of bulk bcc Fe. This trend is in line with measurements of the 3[ital s] exchange splitting from fcc Fe compared to bcc Fe as well. A 0.25 eV exchange splitting is observed in the 3[ital p] core level.
