Neutrons can be produced through nuclear
techniques.

with matter. They can also be produced by
interaction of high-energy photons about with
matter (photoneutron reaction). The
photoneutron reaction typically requires
photons with energy in excess of 10 MeV.

Muons
Muons are particles that are physically similar
to electrons, but about 200 times heavier.
a. Muons are produced by several
mechanisms and require photon energies
greater than 212 MeV or proton energies
greater than 140 MeV.
GeV = 1x109 eV
b. Muons are not usually seen in significant
amounts at machines with energies less
than 1 giga electron-volt (GeV).
