Abstract
Excitation of atoms by ion impact is analyzed for such collisions where only the Coulomb field of the ion affects the excitation process. At intermediate energies, electrons bound to the atom are promoted on the saddle of a two-center Coulomb field, where they are dynamically stabilized by a Paul-trap-like mechanism. These excitation processes lead to transient atomic states with large electric dipole moments. By measuring the intensity of HeI spectral lines induced by 10–500-keV protonhelium and 65-MeV Arq +-helium (q = 6 and 13) collisions as a function of an electric field Fz applied to the collision volume, the electric dipole moments predicted by the Paul-trap model were detected.
