Abstract
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 14p 1 and Xe2 4d 15p 1 doubly charged ion states are observed, and also Kr 3d 14p 1nl and Xe 4d 15p 1nl 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 calcu- lations performed with an algebraic Green’s-function method, and also with previous experimental information from Auger electron spectroscopy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
