✦ Synopsis

Electron energy-loss spectra. obtamrd for Ne and Ar, are analysed tn terms of Compton profiles (CPs). The euperimental CPs do not peak at q = 0, nor are they symmetrtcal as to theu maxImum value, as predlcted withm the framework of the lmpulsc approuunatlon.

Thus Yompton defect" IS charactertsed by a shaft parameter w and an asymmetry parameter 69, and IS mvcstlgated as a function of momentum transfer K. A quahtahve comparison IS made with theoretical predicsons for the Compton defect We also emphasize the K range where partial or total K-Independent CPs of the w=et may be detcrmtned
