Title: Laser-field enhanced electron transfer in p-Ne and p-Ar collisions

Abstract

Electron transfer in the presence of a laser field is considered for the p-Ne and p-Ar collision systems. The calculations are based on a time-dependent density functional theory framework and the basis generator method for orbital propagation. Significant enhancements of electron transfer at low collision energy are found and interpreted with the help of molecular potential curves. For the p-Ar system a moderately intense field at 800 or 1064 nm wavelength is sufficient to increase the total cross section by more than a factor of 2. Contrary to previously studied cases this scenario can be realized and tested in the laboratory.

  • K x rays have been observed in low energy collisions of bare Kr, Ar, and Ne ions with a neutral gas target. Although largely neglected previously, we have found that multiple-electron transfer processes play a significant role in shaping the x-ray spectra. The observed ratios of normal-satellite to hyper-satellite line intensities are found to be roughly independent of the ion species and much larger than those estimated from previously reported electron transfer cross sections, suggesting that there may be a strong correlation between two electrons during the electron transfer or during the subsequent cascades. It is suggested that exact knowledgemore » of the initial and final principal and angular momentum quantum numbers (n,l) in electron transfer are the most essential missing ingredients for understanding the entire x-ray emission process in astrophysical, laboratory, and technological plasmas.« less
  • We demonstrate the presence of femtosecond laser induced charge transfer in Ne{sup +}-He collisions. Electron transfer in ion-atom collisions is considerably modified when the collision is embedded in a strong laser field with the laser intensity of {approx}10{sup 15} W/cm{sup 2}. The observed anisotropy of the He{sup +} angular distribution confirms the prediction of early work that the capture probability varies significantly with the laser polarization angle.
  • Following Jones and Dahler (Phys. Rev. A 37, 2916 (1988)) we study the theory of the process of ionization within the framework of the Feshbach projection-operator formalism, with the discrete fine-structure states (before ionization) and the continuum states (after ionization) as the two separate subspaces of Hilbert space. For the Ne{sup *}(3{ital s})-Ar and Ne{sup **}(3{ital p})-Ar systems we have calculated {ital ab} {ital initio} autoionization widths. In the approximation in which only two electrons play an active role, the coupling matrix element between the two subspaces is a linear combination of two-center two-electron integrals for the exchange and themore » radiative mechanisms. In general, our calculations support the semiempirical results of Morgner (J. Phys. B 18, 251 (1985)) for the coupling matrix elements as derived from experimental data. The autoionization widths {Gamma}{sub {ital J}{prime},}{ital J{Omega}} are presented for initial states {vert bar}{ital J},{Omega}{r angle} of the Ne{sup *(*)} atom and final states {vert bar}{ital J}{prime}{r angle} of the Ar{sup +} ion. They show a pronounced {Omega} dependence and a strong correlation of initial and final states, e.g., {vert bar}0,0{r angle}{r arrow}{vert bar}3/2{r angle} and {vert bar}2,2{r angle}{r arrow}{vert bar}3/2{r angle}. For the Ne{sup *}(3{ital s}) states the two-center two-electron calculation is in good agreement with the two-state basis of Driessen {ital et} {ital al}. (Phys. Rev. A 42, 4058 (1990)), based on a one-electron overlap approximation. In a semiclassical model the polarized-atom ionization cross sections are calculated. For the Ne{sup **}(3{ital p})-Ar system the energy dependence of both the polarization effect and the average cross-section value is reproduced very well, in contrast to the one-electron approximation.« less
  • Nonstatistical enhancements for formation of the metastable 1s2s2p {sup 4}P state compared to the similarly configured 1s2s2p {sup 2}P{sub -} and 1s2s2p {sup 2}P{sub +} states are observed following single electron transfer to C{sup 4+}(1s2s {sup 3}S) and double electron transfer to C{sup 5+}(1s) ions, respectively. Previously, similar enhancements were observed in the population of the {sup 4}P metastable state resulting from electron transfer in {approx}1 MeV/u F{sup 7,8+}+He and Ne collisions [J. A. Tanis et al., Phys. Rev. Lett. 92, 133201 (2004)]. The enhancements were attributed to a dynamical Pauli exchange mechanism involving projectile and target electrons having themore » same spin alignment. Recently, it was suggested that the enhancement might be due to cascade effects following electron transfer to states with n>3. To further understand the observed enhancement of the {sup 4}P state, new investigations of Auger emission spectra in collisions of 0.5-1 MeV/u C{sup 4,5+} with He and Ne targets have been conducted. Experimental ratios of the resulting {sup 4}P intensities to the sum of the {sup 2}P{sub -} and {sup 2}P{sub +} intensities for the collision systems studied give values three to four times larger than expected based solely on spin statistics for single transfer to C{sup 4+}(1s2s {sup 3}S) and double transfer to C{sup 5+}(1s). Theoretical calculations suggest that about half of the observed enhancement is caused by cascade effects.« less
