Theoretical study of Doniach and Sunji<S (DS) on [K-ray photoemission spectra(XPS) is extended beyond the behaviour precisely at threshold. A perturbatic>nalcalculation where the static hole potential is present only after photoemission isperformed to the fourth-order term based on Mizuno and Ishikawa's model.The anomalous exponent ox in DS theory is found to laave a correction term wltichis linear in coy -co. Here, Ict>is the energy of an e?nitted electron and Ictcp thethreshold energy. This correction term is appreciably large at finite distances fromthreshold. Exponents experimentally obtained away from threshold are differentby nature from those given by DS theory.
