Abstract
The enhancement effect observed by Peisach and his co-workers [Nucl. I nstr. and Meth. B 75 (1993) 14] in thick target PIXE measurements on t ransition metal fluorides was demonstrated to occur on targets contain ing no fluorine at all. On the basis of the very characteristic backgr ound shape the enhancement was attributed to the charging up of the in sulating target. Using a hot carbon filament both the charging and the enhancement were possible to eliminate. The time course of the whole phenomenon was also monitored.
