Alignment of beam-foil excited fast (MeV) molecular ions from defined electronic configuration

Collisions at MeV energies of molecular, heavy ions with gaseous and with solid matter are used to create highly excited and highly ionized collision partners. After the collision the molecular, heavy ions separate via Coulomb explosion. They impose their kinematics to both the molecular fragments and to the Auger electrons emitted from the excited fragments. The angular distribution of the Auger line-shape yields information on directional effects of specific configurations of the system. (author)
