Electron-atom/molecule/condensed matter interactions
Excitation and ionization of atoms due to their interaction with low energy electrons is studied using electron-polarized photon and electron-electron angular correlation techniques, respectively. The excitation studies have led to a quantum mechanically complete description of the excitation process and work is well advanced on the study of ionization at this fundamental level.
Superelastic electron scattering from specific laser excited ro-vibrational states of molecules are also being set up to yield the first detail at this level on molecular excitation. Correlation studies yielding simultaneous energy and momentum information on condensed matter bands will complement the work of our theoretical colleagues.
