Description

We study the dynamics of an invariant set of the classical Coulomb atom, which generalizes the one Langmuir proposed for helium in 1921. The n electrons are positioned at the vertices of a regular polygon that changes size homothetically, while the nucleus moves along a line orthogonal through the centre of the polygon. Our main result is that for negative energy the equations of motion have infinitely many periodic solutions
