Equivalent to an H+ ion, for 10 points, name this particle with mass of 1 amu and chargeof +1, which resides in the nucleus alongside the neutron.
These particles collide with their own antiparticles in an accelerator which detected the top quark at Fermilab. They are emitted along with carbon-14 when cosmic rays strike nitrogen nuclei in the atmosphere, and they can be used toelucidate chemical structures in their namesake type of NMR. They are converted into a particle with nearly thesame mass while emitting a neutrino in a form of beta decay called electron capture. They are composed of two up quarks and a down quark.
