✦ Synopsis

The electronic excitation in atom-atom collisions is treated by describing the heavy particle motion in the Born approximation.

To deal with Ihe electronic wavefunction it will be in many casts a reasonable first ;Ipprosimation to assume il one-electron model for one ntom and kerp the other atom in the initial state. In this :!lodcl the scattering amplitude is sho\vn to depend only on the interaction of this one elecrron with the rarget and the form-factor of the respective states. Calculations for this one-electron model are presented, showing rm oscillatory behsviour in the integral cross section. These oscillations are due to the electron-target interaction.

The results are in good agreement with esperimental data.
