“…The accuracy of the ion-beam energy is of the order of 0.1%%uo. This introduces an additional systematic uncertainty of the measured cross sections of less than 1% for the lowest energies studied.L3 subshell[43]. From the SCA calculations we found that pM =0.01 and p& =0.10, thus justifying Eq.…”

L-shell x-ray production and subshell ionization cross sections have been measured for 0.4 -1.8-MeV/amu carbon and nitrogen ions for selected heavy elements with 72 & Z~~90. The results yre compared with the predictions of the ECPSSR theory [perturbed-stationary-state (PSS) theory with energyloss (E), Coulomb deflection (C), and relativistic (R) corrections] describing both direct ionization and electron-capture processes and the semiclassical approximation (SCA} calculations for direct ionization.For both theories significant deviations are found for L2-subshell ionization in the low-energy range.The multiple ionization of outer shells was studied by comparing L x-ray intensity ratios measured for heavy ions and protons. The ionization probabilities of the N4 subshell at zero impact parameter was extracted from these data. Measured ionization probabilities are compared with the predictions of the SCA theory and the "geometrical model. " The inAuence of multiple ionization on the measured Lsubshell cross sections is discussed.

L-subshell ionization cross sections in gold and bismuth by 3.6–9.5-MeV carbon and 4.0–7.2-MeV oxygen ions

L-subshell ionization cross sections of Au and Bi induced by C"+ and 0'+ ions have been measured for impact energies ranging from 0.25 to 0.79 MeV/u. The data have been compared with the predictions of the ECPSSR [perturbed-stationary-state (PSS) theory with energy-loss (E), Coulomb deflection (C), and relativistic corrections (R)] theory. Reasonable agreement between theory and experiment is observed for the L&(2s&&2) and L3(2p3/2) subshells. For the L&(2p&z&) subshell, however, large disagreement between the data and the ECPSSR predictions persists. This difference could be due to the "collision-induced intrashell" mechanism that was suggested by Sarkadi and Mukoyama [J. Phys. B 14, L255 (1981)].PACS number(s): 34.50.Fa

“…In a recent work Padhi et al (1995) studied the ionization of the L subshell of Au and Bi through the impact of B ions in the energy range 0.48-0.88 MeV amu −1 . Their goal was to investigate further the anomalies which have been found in previous L-shell ionization works using heavy projectile ions (Li et al 1976, Sarkadi and Mukoyama 1980, Jitschin et al 1983a, b, 1985, Pálinkás et al 1983, Berinde et al 1984, Papp et al 1984, Dexheimer et al 1986, Kambara et al 1989, Semaniak et al 1994, Dhal et al 1995a. In these works large deviations (up to one order of magnitude in some cases) were observed between the measured cross section values (subshell cross section ratios) and the predictions of the first-order ionization theories.…”

Coupled-states calculations have been made to interpret the L-subshell ionization cross section data measured by Padhi et al for collisions of B ions with Au and Bi in the energy range 0.48-0.88 MeV amu −1 . The calculated cross sections are in a reasonable agreement with the measured values. It has been shown that simple static Stark mixing of the target 2s and 2p atomic wavefunctions is inadequate for the description of the ionization process, and the dynamical treatment of the subshell couplings based on the solution of the coupled equations of the problem is necessary for the satisfactory description of the process.
