“…At higher energies our cross sections are within the error bars of the measurements by Detleffsen et al [60]. As to electron transfer to the 2s state ( Figure 5), our cross sections are in agreement with the experimental data of Bayfield et al [62], Chong et al [63], Hill et al [64] and Morgan et al [57]. But in the 40-100 keV energy interval our results are located between the values given by Bayfield et al [62] and Ryding et al [65].…”

The semiclassical convergent close-coupling approach to ion-atom collisions has been extended to include electron-transfer channels. The approach has been applied to study the excitation and the electron-capture processes in proton-hydrogen collisions. The integral alignment parameter A20 for polarization of Lyman-α emission as well as the cross sections for excitation and electron-capture into the lowest excited states have been calculated in a wide range of the proton impact energies from 1 keV to 1 MeV. The results are in good agreement with experimental measurements.

“…This work supports the existence of distortion effect in electron excitation to bound states of the target as predicted by Bugacov et al [25].Tong et al [26] studied the excitation and charge (including resonant charge transfer) transfer processes of H + and H collisions in a wide range of collision energies by solving the time-dependent Schrodinger equation which is solved by the split-operator method with a generalized pseudospectral (non uniform grid) method. The calculated impact excitation and charge transfer cross sections are in reasonable agreement with the available experimental measurements, Tong et al [26], Morgan et al [27], Chong and Fite [28], Stebbings et al [29], Kondow et al [30]. Electron excitation to H atom from n = 2 to n = 3 states in 1-300 keV/amu He 2+ + H collisions is studied by Fritsch et al [31] within the semiclassical close-coupling method with AO basis sets.…”

Electron excitation of hydrogen atom by ions impact in the energy range 20–1000 keV/amu

We have calculated the electron excitation cross sections of hydrogen atom by the impact of protons, alpha particles and He + ions using the boundary corrected continuum intermediate state approximation in the intermediate and high energies. The calculated results are compared with other theoretical and experimental results. The angular influence of excitation to the H atom at the intermediate energy is also discussed. The distortion effects due to the projectile charges in reactions of electron excitation to bound states of the target H atom are shown in the intermediate and high collision energy.

“…In the last sixteen years there have been a number of experiments (Lockwood & Everhart 1962, Helbig & Everhart 1965Stebbings et al 19^5> Ryding et al 1966;Young et al 1969Young et al , 1970Kauppila et al 1970;Morgan et al 19735 Houver et etal. 1976;Chong & Fite 1977;Park et al 1978). Theoretically, there ar of approaches, which are more likely to be valid at high energies (>; 25keV) but which are frequently quite accurate in the intermediate energy range, perhaps down to lOkeV.…”

A multistate molecular approach to the proton—hydrogen collision is formulated in terms of an impact parameter perturbed stationary-states approximation. Spurious long range couplings are avoided and Galilean invariance is enforced by the inclusion of momentum translation factors which are determined variationally within an Euler-Lagrange formalism (Crothers & Hughes 1978). Well defined radial and rotational coupling matrix elements are employed in the 1-7 keV impact energy range in a six-state (lso g , 2po u , 2pπ u , 3po u , 3pπ g , 4fo u ) calculation of elastic and inelastic differential scattering cross sections, charge exchange probabilities and both direct and exchange H (2p) production total cross sections. They are also employed in the same energy range in a ten-state (1so g , 2po u , 3dπ g , 2pπ u , 2so g , 3po u , 3do g , 4fo u , 4dπ g , 3pπ u ) calculation of both direct and exchange H (2s) production total cross sections. The results are in excellent accord with experimental data and show considerable improvement on previous molecular calculations. This success is attributed to the inclusion of both momentum translation factors and radial coupling matrix elements.
