Electron impact ionization remains a cornerstone experimental and theoretical technique in atomic, molecular and biological physics. The process involves an incident electron colliding with an atom or ...

An international team of physicists has calculated the efficiency of a reaction involving an incoming electron kicking out an electron from the metal beryllium (Be) or its hydrogen compound molecules, ...

The study of ionisation cross sections and X‑ray production induced by electron impact forms a cornerstone in our understanding of atomic interactions and material characterisation. Ionisation cross ...

Mass spectrometers can now be operated at pressures in the proximity of those applied in most plasma processing systems due to the availability of particle detectors capable of being used at pressures ...

A strong laser beam can remove an electron from an atom – a process which takes place almost instantly. This phenomenon could now be studied with a time resolution of less than ten attoseconds (ten ...

During the analysis of NH 3 in H 2 O gas streams, a big issue when trying to detect low NH 3 levels arises due to the spectral overlap between the m/z 17 of both NH 3 and water. The water background ...

In a new study published in EPJ D, researchers have clearly identified particular areas where discrepancies arise between theoretical and experimental measurements of helium ionization by an impacting ...

There are various ways to create artificial diamonds, but a new method developed by researchers including those at the University of Tokyo yields some extra benefits. By specially preparing samples ...

The availability of particle detectors which can be used at up to 4x10-4 Torr pressures has made it possible to use mass spectrometers at pressures close to those used in several plasma processing ...
