Preliminary evidence for the hypothesis that the electron is not an elementary particle

  • 10 תגובות
Led by researchers from the Institute of Physics at Princeton University, an initial discovery has been published that strengthens the controversial hypothesis that the electron is made up of two elementary particles: one carries a negative electric charge and the other the electron's spin. If the interpretation is indeed correct, the assumption that is more than a century old may be erased and make waves in the scientific community.

Simulation of the experiment in which the first images of a quantum electronic crystal were obtained, the existence of which was predicted 80 years ago. The researchers saw electrons arranged as pearls in a string (red balls) along a nanowire. To observe the electrons without affecting them, a single electron (in green) carried by another nanowire was used as a sensor (scanning detector) that detected the electric fields created by the electrons in the crystal

The scientists took advantage of the fact that chirality affects an electron property called "spin", which is characterized by two states - "spin up" and "spin down" - similar to the spinning of a spinning top clockwise or counterclockwise. Illustration: Prof. Ron Naaman, Weizmann Institute

In the background is the structure of a krypton atom in the classical state where 36 electrons are arranged in a kind of shells. The researchers measured the oscillations in the quantum state (front, in pink) on the outside of an ionized krypton atom and the oscillations that cause the atom to move.
