Abstract
Polarized)(AS measurements at the L-3 copper edge were performed on single crystals of Sr14-xCaxCu24O41 (x=0,12) and on new compounds (Sr,Ca)(0.5)CuOz grown by Molecular Beam Epitaxy. The absorption spectra for these two fami lies are very similar, and completely different from those observed on CuO2 cuprate compounds. Doping of the thin films is varied in a wide range inde pendent of the alkaline Sr/Ca ratio.
