Making use of the direct solution for Schrödinger equation, the impact excitation of hydrogen atoms by proton and anti‐proton is studied. For the trajectory of projectile particles, we apply the straight line as well as curved trajectory. In order to save the number of glid, we employ the split‐operator method and pseudospectral (non‐uniform mesh) in energy representation. The calculations are compared with previous works of the traditional closed coupling impact parameter method and that of direct solution method. Comparison between the results of proton and anti‐proton impacts are physically discussed.
