Gold L-shell ionization probability by 1 MeV proton at large scattering angles

The impact parameter dependence of the ionization of Gold L-subshells has been measured and compared to theoretical values calculated in the SCA framework by Aashamar. Special attention has been paid to large scattering angle measurements and results are obtained for theta(lab) = 30, 45 65, 90, 110, 130, 153 and 166 degrees. Taking into account the sum of Lsub(α), Lsub(β), Lsub(γ), Lsub(l) lines we conclude firstly that the experimental ionization probability P(b) is in good agreement with the theoretical values. Secondly, comparing experimental and theoretical intensy of (Lsub(α) + Lsub(l)) and (Lsub(γ) + Lsub(β)) X-ray lines, we show that ionization of L2 and L3 subshells is also fairly well described by the SCA model
