Two photons are released when these particles annihilate with an electron. For 10 points each:
[10m] Name these particles which are released along with an electron neutrino in beta plus decay.
ANSWER: positrons [prompt on anti-electrons]
[10e] Positron emission occurs when beta plus decay occurs inside this object. This center of the atom contains protons and neutrons.
ANSWER: nucleus [or nuclei]
[10h] Positrons are also formed in this process, in which a boson becomes a particle and its antiparticle. The opposite of annihilation, this process is represented by a squiggly line splitting into two straight lines on a Feynman diagram.
ANSWER: pair production
