10-Year Study Shows Electron Is Surprisingly Spherical

Facebook Twitter LinkedIn Email Comments
LONDON, May 26, 2011 — Using a very precise laser, physicists have made the most accurate measurement of the shape of an electron, deeming it 0.000000000000000000000000001 cm from being perfectly round. This means that if the electron were magnified to the size of the solar system, it would still appear spherical to within the width of a human hair. Physicists from Imperial College London's Centre for Cold Matter studied the electrons inside molecules called ytterbium fluoride. Using a very precise laser, they made careful measurements of the motion of these electrons. If the electrons had not been perfectly...Read full article
