The photoabsorption spectra and photoelectron yield spectra for the enzymes trypsin, ribonuclease, and lysozyme were measured in the vacuum-uv region between 1050 and 2400 Å. The energy distribution ...

For the first time, and contrary to popular belief, scientists measured the vibrational structure of hydrogen and helium atoms by X-rays. The results disprove the misconception that it’s impossible to ...

Overlapping photoelectron lines and Auger features are a common issue in the analysis of complex materials. The standard approach of switching to an achromatic Mg X-ray source may become undesirable ...
