Charge state effect on K-shell ionization of aluminum by 600–3400 keV xenonq+ (12 &lt; q &lt; 29) ion collisions

“…As we know, the binding-energy modification to BEA is based on the model that a transient quasi-molecule [4,9] will be formed during the inter-nuclear distance between an incoming ion and a target atom shrinks. In this model, the inner-shell electron will be ionized from the united-atom state [18][19][20].…”

“…N P is the total amounts of incident ions measured from target current corrected to the secondary electron emission. The true current can be estimated by I = I target 1 + γ/q (Song et al, 2011). Detection efficiency ε corresponding X-ray energy is 51% and 68% for Kr L α and Au M α X-ray, respectively.…”

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.

“…In order to obtain detailed understanding of the exotic hollow atom, the x-ray spectra [9][10][11][12][13][14][15][16][17][18][19][20][21] and the Auger electron spectra [22][23][24][25][26][27][28][29] during its formation and decaying have been investigated intensively over the past 20 years by several groups. Up to now reasonable agreement has been obtained regarding the formation of hollow atoms in the HCI surface interaction [30,31].…”

X rays originating from transitions from high Rydberg states to the M shell (here called Rydberg-to-M-shell x rays) have been measured in the interaction of Xe1 ' 1 (q = 27-30) ions with aluminum, molybdenum, and beryllium surfaces in the energy range of 350-600 keV, by using a Si(Li) detector. The transition energy calculation by Cowan's program with relativistic correlation indicates that such x rays are mainly from the transition of the higher quantum states, with the principal quantum number from 6 up to 30, directly to M shell of xenon. The yield of the x ray per vacancy in M shell decreases slightly with increasing the projectile energies and is inversely proportional to the work functions of metallic surfaces used. However, it increases rapidly with the increase of the projectile charge states. All of these experimental facts combined with the transition rate calculations indicate that the measured Rydberg-to-M-shell x rays come from the "above the surface" hollow Xe atoms or ions deexcitation, when the inner shells such as N and O have not been filled.
