Using a resonatorlike electrostatic ion trap, we demonstrate that, under certain conditions, it is possible to keep the width of a packet of ions oscillating between two mirrors constant. We show, using a one-dimensional model, that the effect is the result of Coulomb repulsion, which, in a counterintuitive way, keeps the ions together.
