X-ray production cross sections induced by neon ions

Au L-shell x-ray emission induced by 154.3–423.9 MeV/u C6+ ions

“…Therefore, it is of great significance to further study the x-ray emission induced by high energy heavy ions.The characteristic x-ray emission, the consequential result from the decay of the projectile ion or inner-shell vacancies produced by collision of energetic ion with atom, provides important information to the arrangement of atomic orbital electron and inner shell process in collisions. In the low and intermediate energy region, a great deal of experimental works have been carried out focusing on such process by x-ray measurement [13][14][15][16][17][18] , and many well-known theories have been developed to describe such inner-shell ionization, such as, binary encounter approximation (BEA) 19 , plane wave Born approximation (PWBA) 20 , modified PWBA model by energy-loss, Coulomb-repulsion, perturbed-stationary-state and relativistic (ECPSSR) and refined ECPSSR at low energies with modification of united and separated atom approximation (ECUSAR) [21][22][23] . However, only a limited number of studies have been undertaken in the very high energy region, especially for the fast ions with energy greater than one hundred MeV per mass unit (MeV/u) [24][25][26][27][28] .…”
