H/T Yolanda Aaliyah Physicists at the Max Planck Institute for Nuclear Physics in Heidelberg have filmed the pulsing motion of the electron pair in a helium atom. At 15.3 femtoseconds (fs) the two electrons are close to the nucleus (centre of image) and then move away from it. The colour indicates the probability of finding one electron at position A (vertical axis) and the second electron at position B (horizontal axis) on a line drawn through the atom (along the polarisation direction of the laser). At 16.3 femtoseconds they arrive back at their original position again; they thus move with a beat of around one femtosecond.
