SLOPING SHIRLEY-TYPE INELASTIC LINE-SHAPES

A simple modification to the Shirley-type inelastic line shape is prop osed. The modification results in a sloping background contribution (' tail') and a non-infinite inelastic tail area. Far from the photopeak the present tail shows Tougaard-type behaviour, but in the vicinity of the photopeak it deviates significantly from the Tougaard-type tail U sing the 'universal' constants derived in the frame of the Tougaard mo del, universal 'tail height' and 'tail slope' parameters are derived.
