Title:	Comment on "Variation of Cu-O charge-transfer energies in YBa2Cu3O7-x thin films studied by photoemission spectroscopy"
Authors:	Rao, C N R Santra, A K Sarma, D D
Keywords:	oxidation photoemission spectroscopy Cu-O charge-transfer energy satellite intensity YBa2Cu3O7-x

Abstract:	It is pointed out that the change in the oxidation state of Cu in YBa2CU3O7-x with increasing x vitiates the trend in the Cu(2p) satellite intensity and hence the Cu-O charge-transfer energy. When Y is partly replaced by Ca, however, the satellite intensity and T(c) decrease with the increase in Ca content or hole concentration, just as in other cuprates.
