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 ...

Advanced mathematical analysis of the ionisation of a helium atom by an impacting proton has revealed where discrepancies arise between experiments and existing theoretical calculations of the process ...

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 ...

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 ...
