Peer reviewedGreenberg, Richard; Davis, Donald R. – American Journal of Physics, 1978
Describes a dynamical system which is stable at potential maxima. The maxima, called L-4 and L-5, are stable locations of the restricted three-body problem. Energy loss from the system will tend to drive it away from stability. (GA)
