Data: | 2018 |
Resum: | In a central force system the angle between two successive passages of a body through pericenters is called the apsidal angle. In this paper we prove that for central forces of the form f(r)∼λr-(α+1) with α< 2 the apsidal angle is a monotonous function of the energy, or equivalently of the orbital eccentricity. |
