Abstract
AbstractPhotoelectron angular distributions (PEAD) of 2H‐NbSe2 were studied by using a display‐type spherical mirror analyzer (DIANA) and circularly polarized light. Forward focusing peaks in a wide acceptance angle of ± 60° are clearly observed. The forward focusing peaks in the two PEAD patterns taken with clockwise (cw) and counterclockwise (ccw) circularly polarized light show the three‐dimensional atomic arrangements around specific atoms. Three‐dimensional atomic arrangements up to at least the third nearest‐neighbor layer atoms upon the Nb layer were observed. The characteristic of this experimental method is the full application of the forward focusing peak rotation due to the exciting circularly polarized light. Copyright © 2006 John Wiley & Sons, Ltd.
