Abstract
Core-level photoemission peaks taken on several insulators with spatia l resolution of 30-300 mu m rigidly shift in energy from place to plac e, most likely because of local charging effects. Such phenomena can a ffect the linewidth and the general lineshape of conventional, spatial ly integrated spectra even when a flood gun is used, which is one of t he standard remedies against charging. This may require a critical rev ision of photoemission linewidths and lineshapes for many past experim ents on insulators.
