Charge Exchange of Proton Sodium Atom Collision

The coupled static approximation is modified for the first time to make it applicable to multi-channels problem of the collision of the proton by alkali atom. The possibility of producing more hydrogen during the proton-alkali atom collision is investigated. The formation of hydrogen H(1s) and excited hydrogen (in 2s- and 2p-states) of the scattering of the proton by sodium atom is treated for the first time to test the convergence of our method. The modified method is used to calculate the total cross-sections of seven partial waves ( , where is the total angular momentum) at incident energies between 50 and 1000 keV. Our p-Na results and those determined by previous authors are in reasonable agreement.
