This paper is focused on showing that the fully differential cross section of ionization during a collision of a proton and an antiproton with a hydrogen atom is directly expressed by the wave function in the coordinate representation. Wave function is converted from impact parameter representation to momentum transfer representation. In this case, the calculated wave function corresponds at a certain projectile angle of scattering. The square representation of this wave function module shows how the angular distribution of ionized electrons varies over time. The ionized electron's flow is directly visible from the image. In addition, the direct differentiation of the fully differential ionization cross section by the wave function is shown to be consistent with the effective time determined by the ionization amplitude, which is the traditional method.
