El antineutron es tambien neutro, pero de forma distinta: tiene 2 quarks positivos y uno negativo, mientras que el neutron posee 2 negativos y uno positivo.
The fact that the neutron had a magnetic moment, incidentally, showed that such a thing as an antineutron could exist, which would have a magnetic field pointed in the direction opposite to that of the neutron.
The new antinucleus, discovered at RHIC's STAR detector, is a negatively charged state of antimatter containing an antiproton, an antineutron, and an anti-Lambda particle.
One would be the neutron, of course, but the other, as was shown in 1956, would have to be an antineutron.
Each antimatter atom has antielectrons (positrons), antiprotons, and antineutrons, except the antiatom of ordinary hydrogen which has no antineutron.
The study provides insight into the structure of antimatter nuclei, which consist of bound antiprotons and antineutrons.
The debris of these collisions might also yield exotic particles like pions, kaons, antiprotons and antineutrons, which may provide scientists clues to physics beyond the (http://home.
For example, an atom of unmatter is formed either by electrons, protons, and antineutrons, or by antielectrons, antiprotons, and neutrons.
