Research overturns accepted notion of neutron's electrical properties

Physics.org-feed

For two generations of physicists, it has been a standard belief that the neutron, an electrically neutral elementary particle and a primary component of an atom, actually carries a positive charge at its center and an offsetting negative charge at its outer edge.

Gerald A. Miller, a UW physics professor, has found that the neutron has a negative charge both in its inner core and its outer edge, with a positive charge sandwiched in between to make the particle electrically neutral.

The text-book interpretation of these form factors is that their Fourier transforms are measurements of the charge and magnetization densities. But the initial and final nucleons have different momentum, and therefore different wave functions. This is because the relativistic boost operator that transforms a nucleon at rest into a moving one changes the wave function in a manner that depends on the momentum of the nucleon. The presence of different wave functions of the initial and final nucleons invalidates a probability or density interpretation.

Begrijp ik nu goed dat er iets verkeerd was aan de klassieke analyse? Om ten gronde te begrijpen hoe dat zit moet men allicht het technische deel van het artikel in detail bekijken?
