Study of Kβ to Kα X-ray intensity ratios induced by 84.5 MeV 12C4+ ions

This experiment was completed in the National Laboratory of the Heavy Ion Research Facility in Institute of Modern Physics, Chinese Academy of sciences, Lanzhou. The K-shell X-rays arising from Cu, Mo, Ag, Cd, In, Sn, W, Au targets bombarded by 84.5 MeV 12C4+ ions have been measured by an ORTEC HPGe X-ray detector. The intensity ratios of Kβ to Kα X-ray arising from all of the metal targets measured in the present work were worked out and compared with the theoretical values which have been calculated by Scofield using Hartree-Fock-Slater wave functions as well as the experimental results obtained by other methods (such as decay radiation, target bombardment by photon, electrons, proton and so on). The comparison results show that the intensity ratios of Kβ to Kα X-ray arising from the metal targets following bombardment by 84.5 MeV 12C4+ ions used in the present work were distinctly larger than the theoretical values and the other experimental values.
