High resolution electron beam sources combined with mass spectrometry allow to gain insight into the processes of low-energy electrons. Our research focuses on: Anion formation from molecules: We are ...

will be able to see the time reverse of the process which is double ionization by a single photon. Tanis has been active in the field of atomic collision physics, investigating fundamental ...

It describes options and how to calibrate plane parallel ionization chambers, against air kerma or absorbed dose to water standards at cobalt-60 gamma ray energies. The use of these chambers to ...
