| Summary: | We measured spectra of low energy electrons emitted in the interaction of singly charged Ne<sup>+</sup> ions with the Mg surface at incident ion energies ranging from 50 eV to 4 keV. The study examines issues related to the excitation of both the surface and the bulk plasmons of the target. We will also focus on the dynamics of the production of the singlet Ne2p<sup>4</sup>(<sup>1</sup>D)3s<sup>2</sup> and triplet Ne2p<sup>4</sup>(<sup>3</sup>P)3s<sup>2</sup> autoionizing states of projectiles scattered in a vacuum. The threshold behavior of the autoionization lines show that double excitation occurs simultaneously in a single scattering. The predominant excitation of the triplet state indicates the importance of charge rearrangement and the electron correlation effects during the collisional excitation. |
