Abstract
The energy distributions of secondary electrons emitted by targets bombarded with ions in the range 10–100 keV, are studied. The energy spectra show an intensive peak at 2 eV. Beyond, in the experiments performed on light elements (Z ≤ 30) we observe an Auger peak relating to the creation of a hole on the fxst atomic energy level situated below the valence band (KVV, L23 VV and M23 VV transitions) accompanied by two or three peaks corresponding to excitation of surface plasmons. Energy spectra obtained from phosphorus and sulphur compounds reveal Auger electrons corresponding to L23(P) VV (or L23(S) VV) and L23(P) MIV-V(Ga) V (or L23(P) NIV-V(In) V) transitions; moreover peaks due to plasmon excitations and d band excitations can be distinguished. The fnst results obtained from some alloys show Auger spectra, characteristic of the different elements which compose the alloy. An anisotropy in the energy angular distribution of secondary electrons emitted from copper single crystal is observed.Keywords
