==Key Stage 5==
===Meaning===
'''Pair Production''' is the process in which a very high [[energy]] [[Gamma-ray|gamma ray]] [[photon]] produces a [[matter]]-[[antimatter]] particle pair.
===About Pair Production===
: '''Pair Production''' occurs most often when a very high [[energy]] [[Gamma-ray|gamma ray]] passes close to a [[nucleus]]. However it can happen at any time in free space.
: During '''Pair Production''' the total [[energy]] of the [[photon]] is converted into the [[Rest Mass|rest mass]] of the [[particle]] pair.
: In '''Pair Production''' [[Conservation of Momentum|conservation of momentum]] is conserved due to the [[momentum]] of the two [[particles]] after the their production.
===Equation===
<math>hf=2E_0</math>
Where
<math>E_0</math> = Rest Mass Energy of each particle
<math>hf</math> = The [[energy]] of [[Gamma-ray|gamma ray]] [[photon]] prior to the production
<math>h</math> = [[Planck's Constant]]
<math>f</math> = The [[frequency]] of the emitted [[photon]]
