Swiss, German physicists split the electron Spin here, orbit there By Richard Chirgwin 19th April 2012 00:01 GMT An international research team has observed an electron being split into two “quasi particles”, one carrying the original particle’s spin, the other carrying its orbital movement. Spin (giving rise to magnetism) and angular momentum (the path the electron follows around the nucleus of an atom) are two out of the electron’s three quantum properties (the other is charge). These properties attach to a single electron – unless, it seems, you pump the right substance with the right amount of energy. <more>
