VUV-PHOTOIONIZATION OF LASER-EXCITED ATOMS

Recent results on the VUV-photoionization of laser-excited atoms obtai ned by photoelectron spectroscopy are reviewed. There are two groups o f experiments: In the first group electron correlation phenomena, espe cially satellite emission, are studied in direct inner-shell photoioni zation processes of unpolarized atoms, whereas in the second group of experiments aligned excited atoms are prepared in order to probe the r esonant excitation of inner-shell electrons to autoionizing resonances .
