Abstract
Ultraviolet and x-ray photoemission measurements have been performed on single-crystal (La1-xSrx)2CuO4 with x=0.0 and 0.04. Considerable differences are found in the photoemission spectra when compared with the results for sintered samples: a single-peak structure for the O 1s level and the absence of the peak at 9 eV of unknown origin reported for sintered samples, etc. Comparison is also made with band-structure calculations.
