“…In the collision energy range considered in the present paper (0.1-100 keV/u), the straight-line approximation for the relative nuclear motion R(t) = b + vt (b is the impact parameter and v is the collision velocity) can be safely adopted due to the small binding energy of the 2p electron of Li. The TC-AOCC equations are obtained by expanding the total electron wave function in terms of bound atomic orbitals, multiplied by plane-wave electron translational factors (ETFs) [15] ( r,t) =…”

State-selective and total single-electron-capture cross sections in collisions of H + with the excited Li * (2p) atom have been investigated by using the full quantum-mechanical molecular orbital close-coupling (QMOCC) method in the energy range 0.001-3 keV/u and by the two-center atomic orbital close-coupling (TC-AOCC) method in the energy range 0.1-100 keV/u. The present results are also compared with data from other sources when available. It is found that the total and partial electron-capture cross sections are sensitive to the initial p-state charge cloud alignment, particularly in the low-energy region.

Electronic energy loss of channeled ions: The giant Barkas effect

et al. 2004

In this work we have measured the electronic energy loss of 9 Be and 11 B ions for the ͗100͘ and ͗110͘ directions in Si as a function of the incident ion energy. The channeling measurements cover a wide energy range between 100 keV/ amu and 1 MeV/ amu. The Rutherford backscattering technique has been employed in the present experiments. An overall compilation of channeling energy loss values for several ions, including those for He, Li, and O measured previously, provides a clear picture of the Barkas contribution to the stopping power due to valence electrons in the present energy regime. A maximum of the relative contribution occurs for Be ions around 250 keV/ amu while a saturation effect is observed for heavier ions. These results are interpreted in terms of a self-consistent nonlinear calculation based on the transport cross-section approach together with the unitary convolution approximation model, which describe the present data reasonably well at high projectile energies.
