Single electron capture by Li3+ from He in low-energy collisions

Mostrar todas las versiones(2)

The total cross section for single electron capture from He by Li 3+ ions has been calculated using the close-coupling technique in the impact energy range 1.5*10-4-43 keV. The model-potential method was used to determine the electronic energy curves of the (LiHe) 3+ molecule. The dynamic couplings...
