A rather complete experimental study of forward and backward electron velocity spectra from thin foils bombarded with ions at constant velocity of 30 atomic units (23MeV u(-1)) was performed. Three different beams (C-12(3+) , Ni-58(14+) and Au-197(36+) and six different targets (C-12 , Al-27 , Ni-nat , Ag-nat , Au-197 and Bi-209 of approximately 90 mu g cm(-2) thickness were used. This procedure allowed to study the evolution of electron emission (velocity and angular distributions) for the [projectile; target] matrix [C , Ni , Au ; C , Al , Ni , Ag , Au , Bi] in a wide angular range. The projectile and target dependence of absolute cross-sections for binary encounter-, Auger- and backward-emitted electrons are analyzed.
