摘要：

Threshold-photoelectron coincidence spectra and threshold-photoelectron spectra are measured for Kr and Xe in the energy regions 105-127 and 75-100 eV, respectively. Kr2+ 3d(-1)4p(-1) and Xe2+ 4d(-1)5p(-1) doubly charged ion states are observed, and also Kr+ 3d(-1)4p(-1)nl and Xe 4d(-1)5p(-1)nl satellite states. To our knowledge, this is the first direct observation in electron spectroscopy of doubly charged ion states where one hole occurs in an inner shell and another in a valence shell. The results are compared with theoretical calculations performed with an algebraic Green's-function method, and also with previous experimental information from Auger electron spectroscopy.
