摘要: Excitation of H+, H2 +, H3 He+, and Ar+ ions by impact on graphite Al2O3 was investigated by means emission spectroscopy in the 50–1000 eV energy range projectiles. Emission Balmer series from excited neutral hydrogen is observed for both targets. In addition, target a continuum emission is observed. The probably originates from MnOm molecules produced collision cascade, when surface atoms bound ionic bonds are released after bond breaking caused neutralization. spectra obtained under -bombardment show Ar II lines emitted backscattered ions.
