X ray emission for 20 MeV to 55 MeV C4+ ions impacting on Cu target
The ionization of the Cu K shell by collisions of C4+ ions at energies ranging from 20 MeV to 50 MeV is studied, and the K x-ray spectra of Cu are measured using an HPGe detector. The relationship between the relative intensity ratio of Kβ and Kα x rays emitted from Cu and the kinetic energy of incident ions is investigated and compared with data for singly ionized atoms. The results show that the relative intensity ratio of Kβ to Kα x ray of Cu target decreases with the increase of incident ion kinetic energy, and the ratio is larger than the data of singly ionized atoms. The K x- ray production cross section of target atom is calculated by using the thick target cross-section formula, and compared with the results obtained from different theoretical models. The results show that the total production cross sections of Kβ and Kα x ray with the increasing incident ion kinetic energy are in close agreement with the BEA modified model which takes multiple ionization into account.
期刊介绍：
Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
