Word	Definition
irradiated	Having been exposed to radiation (as for example by imaging, food-safety sterilization, or a nuclear blast).
attendeenoun	A person who is in attendance or in the audience of an event.
presencenoun	The fact or condition of being present, or of being within sight or call, or at hand.
neutral particle	In physics, a neutral particle is a particle without an electric charge, such as a neutron.
baryonnoun	(particle physics) A heavy subatomic particle created by the binding of quarks by gluons; a hadron containing three quarks. Baryons have half-odd integral spin and are thus fermions. This category includes the common proton and neutron of the atomic nucleus.
nnoun	No
nucleonnoun	A proton (uud) or a neutron (udd).
n0noun	—
subatomic particlenoun	(particle physics) Any of many units of matter smaller than an atom.
prompt neutronnoun	(nuclear physics) A neutron produced immediately by the fission of an atomic nucleus, instead of being emitted by decaying fission products seconds to minutes later; over 99% of all fission neutrons are prompt neutrons (the exact portion depends on the nuclide undergoing fission).
delayed neutronnoun	(nuclear physics) A neutron produced by nuclear fission which is emitted upon the radioactive decay of a fission product nucleus sometime later, rather than at the time of the fission itself. Less than 2% of fission neutrons are delayed neutrons (the exact proportion depends on the nuclide being fissioned).
cold neutron	—
free neutronnoun	A neutron not bound in an atomic nucleus.
thermal neutronnoun	(physics) A relatively slow-moving neutron whose energy is governed by the temperature of its environment.
fast neutron	—
slow neutron	—
epithermal neutron	—
antineutronnoun	(physics) The antiparticle corresponding to a neutron.
quasineutronnoun	(particle physics) A quasiparticle equivalent to a neutron.
protonnoun	(particle physics) A positively charged subatomic particle forming part of the nucleus of an atom and determining the atomic number of an element, composed of two up quarks and a down quark.
