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