This simulation displays the location of the innermost electron in a lead (pb) atom. We are the IPA method which neglects the accumulative effect of the outer electrons.

You may notice that as the particles leave the space, their size and velocity increase by some amount and reset to the center positioon. When they share the exact same point the particles annihilate eachother.
