Abstract
The charge-transfer process is considered for impact energies from 0.025 to 200 keV/amu, using the atomic base matrix formulation represented by time-dependent bases which denote moving atomic orbitals. In the evaluation of the matrix, models of two extreme types, the unitarized model and the absorption model, are introduced. The numerical results show that there is only a small difference between the cross sections obtained using the respective models for impact energies above 0.5 keV/amu, while the cross section due to the unitarized model becomes smaller than one-half of that obtained with the absorption model at an impact energy of 0.05 keV/amu. The data are also compared with other calculations of the same process. For the investigation of the validity of our formula, the unitarized formula is also applied to the processes and . The results are in good agreement with the experimental data.
