X-ray photoelectron spectroscopy is based on the same principle as all photoelectron spectroscopy methods. If a molecule or material is irradiated with light of a known energy above the ionization ...

Recent news that x-ray spectroscopy is being introduced in forensic applications by scientists at Massachusetts' Thermo Scientific Laboratories proves that everything old becomes new again. X-rays ...

An X-ray photoelectron spectrometer is an impressive bit of kit. The relatively low energy of the detected photoelectrons dictates that the experiments are performed in ultra-high vacuum. The ...
