Abstract:
The electron capture in collisions of highly charged O6+ ions with
ground state hydrogen atom is a very important process in the solar
wind X-ray studies. In the present study, the full quantum-mechanical
molecular-orbital close-coupling (QMOCC) method is employed to study
electron capture reactions in collisions of O6+ion with the ground
state atomic hydrogen in the energy region from 10-4keV/u to 5keV/u.
The ab initio multi-reference single and double excitation
configuration interaction (MRD-CI) method is used to calculate the
potential and coupling data used in the QMOCC calculations. Total and
state-selective cross sections for the dominant and subdominant
reaction channels are calculated and compared with the available
experimental and theoretical data. The branching ratios for
Lithium-like O5+ excited ions are used to calculate the contribution
of cascade radiative transitions from n=5 levels to the population of
4l states. From the calculated cross sections, reaction rate
coefficients are obtained for temperatures between 1000 and 1x109K
and compared with other calculations.
Description:
In the present study we employed the full quantum-mechanical
molecular-orbital close-coupling (QMOCC) method to study the dynamics
of this process in detail in the energy range from 10-4keV/u to
5keV/u.
