Ionization of Ar11+ ions during collisions near the Bohr velocity
چکیده انگلیسی

The K-shell X-rays of argon from the collisions of 1–3 MeV Ar11+ ions with V target were measured. It was found that the Kα X-ray shifts to the high energy by 52 eV, and the intensity ratio of Kβ/Kα was larger than the atomic data, owing to the presence of 2p multiple vacancies. The X-ray production cross sections were obtained and compared with BEA, PWBA and ECPSSR theoretical predictions. The BEA model, taking into account the ionic binding energy, coulomb repulsion and multiple ionization effect on fluorescence yield, presented a better agreement with the experimental cross section data.
