So how did the scientists X-ray a lone atom? The atom was hit with X-ray photons. Second, when electrons absorb the X-ray photons, they become excited and tunnel their way to the metal tip of the detector. Being able to identify a material using only one atom could, according to the group, revolutionise research in material science, quantum mechanics, and other areas. They found that as a rare earth metal, the terbium atom maintains its chemical state and is isolated while the iron atom interacts heavily with its surroundings.
