摘要：

Near-threshold photoionization of the Kr 3d and Xe 4d subshells has been studies by measuring the emitted electrons with various fixed energies (0-10 eV) against photon energy. These spectra show peaks corresponding to the Kr(3d)-1 and Xe(4d)-1 ionic states as well as peaks due to the decay of the Kr(3d)-1 nl and Xe(4d)-1 nl core excited Rydberg states. The peaks due to the ionic states are observed to shift to higher photon energy, while their profiles are asymmetrically broadened. Both the effects are attributed to post-collision interaction (PCI). The Rydberg peaks enable accurate calibration of the photon and electron energy scales. The observed energy shifts of the photoelectron peaks and their lineshapes are compared with theoretical predictions of the semiclassical model van der Straten et al.
