Molecular treatment of single-electron capture in Li3++Li collisions
The single charge exchange process in Li3++Li(2s) collisions is investigated in the impact energy range 2.25*10-4-1 keV amu-1. The adiabatic potential energies and radial coupling matrix elements of the Li23+ molecule are computed in a one-electron approximation, using a model potential method. Thos...

The single charge exchange process in Li3++Li(2s) collisions is investigated in the impact energy range 2.25*10-4-1 keV amu-1. The adiabatic potential energies and radial coupling matrix elements of the Li23+ molecule are computed in a one-electron approximation, using a model potential method. Those are subsequently employed to solve the collision dynamics by a full quantum mechanical treatment or by using the semiclassical impact parameter approach. The results for the total electron-capture cross section present a high and broad maximum value around 220 AA2 at 0.1 keV amu-1. A disagreement of more than one order of magnitude with the theoretical results reported by Stollberg and Hai-Wong Lee (1984) is discussed. |
