The density of upper valence band states (U-D0ViS) of amorphous As,Se..)g .in the compositional region of 0$,v'S50 was inves1.igated with ultraviolet )rho-toelectric euvoission spectroscopy. The U-DOVSs in the regions of 0$,v$40 and40$,X'l<50 are well described by 'U-DOVSs synthesized front those of properlyweighted So and As.Se3, and As.Se. and As.Se., r<cspectively. These facts SIIOWtlaat the hetero-bonding is predominant coanpared xvith the houmo-bonding, andthe dominant structure of U-DOVS is deterncined fa"om the structure of the firstnearest neighbour atonts.
