Abstract
The L X-ray production and subshell ionisation cross sections of gold have been measured by proton, alpha particle, carbon, nitrogen and oxygen bombardment in the energy range 0.4-3.4 MeV. These data are compared with the predictions of the plane-wave Born approximation including the binding energy, Coulomb deflection and relativistic corrections. Satisfactory agreement has been obtained between theory and experiment except for the cross sections of the L2-subshell ionisation induced by heavy ions (12C, 14N, 16O). The theory underestimates these cross sections by almost one order of magnitude.
