Charge Transfer Processes of H Atom Collision with Proton, a Case Study by Solving Time-Dependent Schrodinger Equation X. M. Tong, D. Kato, T. Watanabe* and S. Ohtani Cold Trapped Ions Project, ICORP, JST, Axis Chofu 3F, 1-40-2 Fuda Chofu,Tokyo 182-0024, Japan * Physics Dept., International Christian University, Mitaka-shi, Tokyo 181-8585 Japan Here, we present a theoretical study of the charge transfer process of H atom collision with the proton by solving time dependent Schrodinger equation. This is a full quantum, non-perturbation calculation and it services as (1) a test for the numerical method, (2) precursor work for many electron charge transfer process and (3) understanding the dynamic process of the charge transfer process. By decomposing the time-dependent wave function, we can study the detail dynamic information of charge transfer process.
