QUANTUM PHYSICS:
Loopy Electron Model Solves Ion Mystery

Charles Seife

Newton's laws usually fly out the window in the subatomic realm. But now, an international team of scientists has shown that a nearly Newtonian set of electron orbits can explain a puzzling phenomenon discovered a decade ago in which atoms zapped by high-energy lasers absorb far more energy than, on the face of it, atomic theory should allow. On page 902, the researchers show that a Newtonian approach suggested by physicist Richard Feynman holds the key to solving the mystery of the superionized atoms.
