We consider test particle motion in a gravitational field generated by a homogeneous circular ring placed in-dimensional Euclidean space. We observe that there exist no stable stationary orbits inbut exist in, 4, 5 and clarify the regions in which they appear. In, we show that the separation of variables of the Hamilton-Jacobi equation does not occur though we find no signs of chaos for stable bound orbits. Since the system is integrable in, no chaos appears. In, we find some chaotic stable bound orbits. Therefore, this system is nonintegrable at least inand suggests that the timelike geodesic system in the corresponding black ring spacetimes is nonintegrable.
