Abstract The sources TEPOS for slow positrons were installed at the Giessen 65 MeV electron linear accelerator. Ratios of K- and L-shell ionization cross-sections by electron and positron impact were measured on Au-/Ag-foils as function of the incident projectile energy. With energies near threshold a departure is observed of the ratio σ(e−)/σ(e+) from unity (increasing with decreasing energy).
