The purpose of this work is to analyze the dynamics of small body reservoirs under the effects of an eccentric inner giant planet resulting from a planetary scattering event around a 0.5 M star. We carry out N-body simulations assuming that the planets are close to their stability limit together with an outer planetesimal disk. The present work focuses on the analysis of N-body simulations in which a single Jupiter-mass planet survives after the dynamical instability event. Our simulations produce outer small body reservoirs with particles on prograde and retrograde orbits, and other ones whose orbital plane flips from prograde to retrograde and back again along their evolution, which are called Type-F particles. These particles show a correlation between the inclination i and the longitude of ascending node W. Moreover, the range of inclinations that leads to the flipping of an orbit is strongly dependent on the giant planet?s eccentricity.
