We will show that the set of initial conditions leading to collisions and ejections have positive measure and study the capture and escape solutions in the zero-energy case using the infinity manifold. We will also apply the Melnikov method to show that the flow on the zero-energy manifold of another potential which is the sum of the classical Keplerian potential and two anisotropic perturbation which also take into account two relativistic correction terms is chaotic.<\/jats:p>","DOI":"10.1063\/1.4807719","type":"journal-article","created":{"date-parts":[[2013,6,3]],"date-time":"2013-06-03T23:06:56Z","timestamp":1370300816000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Qualitative analysis of the anisotropic two-body problem with relativistic potential"],"prefix":"10.1063","volume":"54","author":[{"given":"Daniel","family":"Pa\u015fca","sequence":"first","affiliation":[{"name":"University of Oradea 1 Department of Mathematics and Informatics, , University Street 1, 410087 Oradea, Romania"}]},{"given":"Cl\u00e1udia","family":"Valls","sequence":"additional","affiliation":[{"name":"Instituto Superior T\u00e9cnico 2 Departamento de Matem\u00e1tica, , Av.
