Abstract
We study a classical model for the atom that considers the movement of n charged particles of charge \(-1\) (electrons) interacting with a fixed nucleus of charge \(\mu >0\). We show that two global branches of spatial relative equilibria bifurcate from the n-polygonal relative equilibrium for each critical value \(\mu =s_{k}\) for \(k\in [2,\ldots ,n/2]\). In these solutions, the n charges form n/h-groups of regular h-polygons in space, where h is the greatest common divisor of k and n. Furthermore, each spatial relative equilibrium has a global branch of relative periodic solutions for each normal frequency satisfying some nonresonant condition. We obtain computer-assisted proofs of existence of several spatial relative equilibria on global branches away from the n-polygonal relative equilibrium. Moreover, the nonresonant condition of the normal frequencies for some spatial relative equilibria is verified rigorously using computer-assisted proofs.
