“…Usually, therole of embeddedprojectiles and adsorbedor contaminant particles as a source of electrons is neglected. Such treatment of the electron emission problem is not correct because, if the measurements have been performed in a differential manner, the presence of such particles is manifested by some structure in the energy and angular distributions (Soszka and Soszka 1983). The surface adsorbed layer essentially determines the features of the ion-electron emission under 'classical vacuum conditions' (Arifov 1969).…”

The energy spectra of electrons induced by xenon ion bombardment of the Fe-Ni alloy target covered by frozen xenon were measured. Three broad maxima superimposed on the background which ranges from zero to a few hundred electron volts were observed. Excluding the first maximum which is a typical maximum of bulk electrons from the metal the yield of electrons shows some angular anisotropy in the region of large detection angles. It is assumed that the emission of these electrons is connected with the creation of the symmetric quasi-molecules Xe++Xe0. The background is associated with direct ionisation of the quasi-molecules during the approach of the collision particles, and the structure of the energy spectrum with outer-shell and inner-shell molecular auto-ionisation processes. The presence of the xenon condensed layer on the metal target was tested by energy analysis of the back-scattered neon ions. The xenon peak and the so-called double-scattering maximum which is attributed to the solid state were found on the energy distribution curve.
