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 ...

Markes International, a world leader in instrumentation for trace organic analysis, has announced the launch of a variable-energy electron ionisation source technology for GC-MS, Select-eV. By ...

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 ...

What are the ionization techniques for mass spectrometry? Mass spectrometry (MS) plays a vital role in many aspects of our lives, from diagnosing illness and detecting food contaminants to fighting ...
