Abstract: | Post form of “boundary corrected continuum intermediate state (BCIS)”
approximation has been employed to study charge transfer cross-sections in collision of Cq+, Nq+ and Oq+ (q=1–5) with ground state atomic hydrogen in the energy range of 50–200 keV/amu. In this formalism we have adopted model
potential for the interaction of the active electron with the projectile ion. Calculated results for total charge transfer
cross-sections have significant improvement over other existing theoretical results in their comparison to the available experimental
findings except for singly charge ions. Sub-shell distribution for total charge transfer cross-section has also been reported
in graphical form. Predictions
suggested by Olson in connection with the sub-shell distribution of total charge transfer cross-section has been reaffirmed.
However, an oscillatory structure of charge state dependence of the total charge transfer cross-sections has not been found
in the present investigation. |
