X-ray emission of C⁶⁺ pulsed ion beams of CSR impacting on Au target

As the C⁶⁺ ion beam pulses, provided by the Heavy Ion Research Facility in Lanzhou-Cooling Storage Rings, impact on Au taget surface, the L_α-and L_β-X spectra of Au atom are measured. Results show that the production cross section of L_α is larger than that of L_β. The production cross sections increase with the kinetic energies of the projectiles. The PWBA and ECPSSR theoretical models are compared with the experimental resulms. The significant difference between experimental data and theoretical models was discussed.
