Atomic collisions

In the past we have also studied ion-atom and ion-molecule collisions of relevance for fusion- or astrophysical plasmas:

• Projectiles: Singly and multiply charged ions
• Targets: Alkali atoms (Li, Na), molecules (e.g. H₂, N₂, O₂, CO)
• Processes: Electron capture, target excitation and ionization
• Methods: Translational energy spectroscopy, photon spectroscopy, Atomic orbital close coupling calculations
