Abstract

A theoretical method to calculate the {ital K}-shell electron-capture cross section in asymmetric collisions is developed. The correlation effect between the active and the passive electrons and the screening effect in the wave function of the active electron are all considered. Under the Oppenheimer-Brinkman-Kramers approximation, an analytical expression for the total capture cross section is obtained. The calculated results for H{sup +}--carbon, nitrogen, oxygen, neon, argon and He{sup 2+}-neon collisions, at the intermediate-energy region, show very good agreement with available experimental findings. A comparison with other theoretical results is given.

Relativistic second-order Oppenheimer-Brinkman-Kramers cross sections for electron capture

Journal Article Moiseiwitsch, B - Phys. Rev. A; (United States)

Cross sections for /ital s/-state to /ital s/-state electron capture from a target atom to a completely stripped projectile ion are calculated using a relativistic form of the second-order Oppenheimer-Brinkman-Kramers (OBK) approximation to the leading order in the fine-structure constant. These theoretical cross sections are compared with the experimental data of Crawford and co-workers (Crawford, Ph.D. thesis, University of California (1979); Gould /ital et/ /ital al/., Nucl. Instrum. Methods B 10, 32 (1985)), analyzed by Anholt (Phys. Rev. A 31, 3579 (1985)), for bare C, Ne, and Ar projectile ions incident with 140, 250, 400, 1050, and 2100 MeV/amu energiesmore »« less

Inner-shell capture and ionization in collisions of H/sup +/, He/sup 2 +/, and Li/sup 3 +/ projectiles with neon and carbon

Journal Article Ford, A; Reading, J; Becker, R - Phys. Rev., A; (United States)

Theoretical methods used previously for H/sup +/, He/sup 2 +/, and C/sup 6 +/ collisions with neutral argon atoms have been applied to collisions of H/sup +/, He/sup 2 +/, and Li/sup 3 +/ projectiles with neon, and to collisions of H/sup +/ with carbon targets. The energy range covered by the calculations is 0.4 to 4.0 MeV/amu for the neon target, and 0.2 to 2.0 MeV/amu for carbon. We calculate single-electron amplitudes for target K-shell ionization and target K- and L-shell, to projectile K-shell, charge transfer. These single-electron amplitudes are used, in an independent-particle model that allows for multielectronmore »« less

Second Born approximation for relativistic electron capture: Exact Monte Carlo calculations for C sup 6+ -Au and Ar sup 18+ -Ag collisions

Journal Article Decker, F - Physical Review, A (General Physics); (USA)

The second-order Oppenheimer-Brinkman-Kramers approximation for relativistic electron capture is formulated, and rigorously calculated {ital K}-{ital K} cross sections are presented for the first time. Theoretical cross sections for electron capture in collisions of C{sup 6+}-Au at 400 MeV/u and Ar{sup 18+}-Ag at 400 and 1050 MeV/u projectile energy are compared with the experimental data and other approximate second Born results. It is shown that exact second Born cross sections grossly overestimate the experimental data.

Double- and single-electron capture and loss in collisions of 1--2-MeV/u boron, oxygen, and silicon projectiles with helium atoms

Journal Article Hippler, R; Datz, S; Miller, P; ... - Phys. Rev. A; (United States)

Single- and double-electron-capture cross sections were measured for 1--2-MeV/u bare B/sup 5+/, O/sup 8+/, and Si/sup 14+/ projectiles in collisions with helium atoms. The measured double-electron-capture cross sections are 2--3 orders of magnitude smaller than corresponding single-capture cross sections. The single-capture cross sections are well described by continuum-distorted-wave calculations. For B/sup 5+/, the double-capture cross sections at high velocities are in reasonable agreement with scaled Oppenheimer-Brinkman-Kramers calculations, assuming capture of independent electrons. Cross sections for electron capture and loss are also reported for nonbare ions (O/sup 6+/, O/sup 7+/, Si/sup 8+/, and Si/sup 13+/). Single-capture cross sections for nonbare ionsmore »« less

Differential cross sections for electron capture from argon by 6-MeV protons

Journal Article Cocke, C; Macdonald, J; Curnutte, B; ... - Phys. Rev. Lett., v. 36, no. 14, pp. 782-785

Differential cross sections for the capture of electrons from argon by 6- MeV protons have been measured as a function of the hydrogen-atom scattering angle between 0.02$sup 0$ and 0.14$sup 0$. Cross sections were measured for capture from all shells and from the argon K shell alone. The differential cross section for K-shell capture does not agree with theoretical results obtained using either the Oppenheimer--Brinkman--Kramers approximation or a Born calculation which includes a contribution from the core--core interaction.
