　　Synopsis Charge exchange (CX) mechanism is popular atomic process for explanation of X-ray emission lines in cometary and planetary objects.Those emission lines are indistinguishable from those created in collisional or photoionized plasmas.However such a complete astrophysical model needs a vast number of CX cross-section.Here, we present a visualized CX model for astronomers with multi-channel Landau-Zener approach to evaluate the CX contribution in observed spectrum.Moreover, we also compare spectrum bashed on the Landau-Zener and with molecular-orbital and/or atomic-orbital close-coupling calculation.
