A new powerful source for coherent VUV radiation: Demonstration of exponential growth and saturation at the TTF free-electron laser
We present experimental evidence that the free-electron laser at the TESLA Test Facility has reached the maximum power gain of 107 in the vacuum ultraviolet (VUV) region at wavelengths between 80 and 120 nm. At s...

Two-Color Experiments on Aligned Atoms
Vacuum-ultraviolet (VUV) photoelectron spectroscopy is well established as an extremely powerful method for investigating many-electron effects in atomic photoionization. Energy- and angle-resolved measurement...

Decay channels of core excitation resonances in 3d and 4f metal atoms
Photoabsorption, photoelectron, and ejected electron spectra of atomic 3d metals and rare earths in the energy range of the strong 3p→3d and 4d→(4fεf) excitations are presented. TheZ-dependence of the strength, s...
