Charge Exchange of Proton-potassium Atom Collision

Abstract

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 p-K collision is treated 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 a range of energy between 50 and 1000 keV. Our p-K results are compared with previous ones.
