X-ray emission induced by 1.2–3.6 MeV Kr¹³⁺ions

Abstract

X-ray emission from Kr 13+ ions in the energy range 1.2-3.6 MeV in steps of 0.6 MeV impacting on an Au target was investigated on electron cyclotron resonance ion source at the Heavy Ion Research Facility in Lanzhou. It was found that a shift of the X-ray lines to the higher energy side occurred. We measured the relationship between the characteristic of X-ray yield of Au M X-rays and Kr L X-rays as a function of incident energy. Furthermore, M-shell X-ray production cross-section of Au induced by Kr 13+ was measured. The measured cross-section of target is compared to the classical binary-encounter approximation and plane-wave-born approximation theoretical model, which is a significant different between experimental and theoretical model.

Kr L X-ray and Au M X-ray emission for 1.5 MeV—3.9 MeV Kr13+ions impacting on an Au target

“…[18,19] In the present work, the results are in accordance with our previous experimental results, in which the same target and different incident energy values were used. [20] In addition, we list the electron configuration transitions of different X-rays. Table 1.…”

Production of projectile and targetK-vacancy in near-symmetric collisions of 60–100 MeV Cu9+ions with thin Zn target

“…In addition, the inner-shell electron excitation, ionization and transfer from one collision partner to the other, during ionatom collisions, have been studied extensively both theoretically and experimentally for many years. [1][2][3][4][5][6][7][8] Particularly, Kshell ionization has been most widely studied for a large range of projectile number and incident energy. However, even today, a complete theory that can predict K-shell vacancy production for all collision systems in different velocities is still lacking, especially at an intermediate energy.…”
