摘要：

The line shapes of multiplet components of the complex x-ray photoemission spectra of the Ta 4f core levels in 1T- and 4Hb-TaS2 are shown to have different asymmetries associated with the charge density wave induced differences in the densities of states at distinct Ta sites which produce site specific local screening of the photohole. This underlines an important general effect in the interpretation of line shapes in x-ray photoemission. © 1995 The American Physical Society.
