Mass and energy analysis of positive ions emitted from metallic targets bombarded by heavy ions in the keV energy region

Abstract: Mass spectra of positive ions emitted from polycrystalline metallic targets (Al, Mn, Co, Ta) were analyzed by the mass spectrometric method when the targets were bombarded by the analyzed Ar+ ion beam of 40-keV energy. Single- and multiple-charged atomic components, as well as single-charged molecular components, were detected. The energy distribution curves for some mass-spectra components, measured by the retarding potential method, are presented.

“…L'étude des distributions énergétiques a souvent été menée à l'aide de dispositifs de filtrage adaptés sur des spectromètres de masse [1], [2]. Cependant, la résolution insuffisante de ces dispositifs ne permettait pas de relever la forme des distributions en énergie des ions en dessous d'une dizaine d'électrons-volts environ.…”
