For three months in 2019, physicists blasted a beam of electrons at lead atoms that were held in place by foil made of diamond. The team was trying to determine the thickness of the neutron skin, the sheath of neutrally charged neutrons that surrounds the positively charged protons in a lead atoms nucleus. They succeeded.
The neutron skin of lead-208 is 0.28 femtometers 0.28 trillionths of a millimetre the team determined, increasing the estimated thickness of the skin by a tenth of a femtometer…
