Abstract
Experimental results of L-subshell X-ray production cross sections induced by the impact of several ions heavier than protons were compiled in order to propose possible scaling laws. The ions of interest in this work are 4He+, 9Be2+, and 14N2+. A feasible universal scaling for the x-ray production cross sections of the Lα (L3M4 + L3M5) line is based on a reduced velocity parameter ξ R L. In this scheme, the experimental data follow well resolved curves for each ion. A similar scaling for the Lγ line (L2N4 + L1N2 + L1N3 + L1O3 + L1O2 + L2N1 + L2O4) is also recommended, based on a different reduced velocity parameter ξ R L1,2. These results appear to be useful for all the studied projectile-target combinations covered in this work, supporting the idea that more theoretical studies in this direction should be done. However, the behavior of the fitting does not seem to follow the previously observed one.
