Their "temperature" is a measure of the kinetic energy of the free variety, and they consist of one up quark and two down quarks.
Ferenc Mezei developed the spin echo spectroscopy of this particle, for which an accurate spectrum may be provided using Bonner spheres. Bruce Cork is best known for discovering its antiparticle, and cold ones can be produced in facilities undergoing their namesake scattering. Their "temperature" is a measure of the kinetic energy of the free variety, and they consist of one up quark and two down quarks. Emitting an antineutrino and electron in negative beta decay, for 10 points, name this particle discovered by James Chadwick that is neutral in charge.
