Argon atom in a Rydberg state

Visualization of an argon atom in a Rydberg state (three spheres) at different points in time, after bombardment by X-ray photons. The circular patterns at left are those formed by the X-rays after they scatter. The three images in sequence show the evolution of the atom in space and time.
