The　gyrocenter of a particle comes slowly close to the planet whereas the particle rotates rapidly around the gyrocenter. When the distance　between the planet and the gyrocenter is several times as short as the Hill radius, the gyrocenter of the particle gradually turns back to the opposite side of the y-axis, as if it were reflected by a mirror. The feature of the scattering is the same as that for the case e=0. For the final impact parameter, bf, and the eccentricity, ef, we have again the relations bf=-bi and ef=ei.
