Just wondering what happens to the excess energy (if there is any) during pair production.

I know that the photon requires >= energy than the combined rest energy of the fundamental particle-antiparticle pair but I just wanted to know what happens to any extra energy.

Thanks in advance

It is transferred to the particles as Kinetic Energy Is this for the AQA Physics Unit 1 exam tomorrow?

Thought it might but I couldn't find it in my text book Thanks

Yeah it is, are you sitting it tomorrow as well?

[DanWoolley]

Yes I am, Got a D in the January exam and want to get at least a C

air Production:- The conversion of a high energy photon into an electron a positron pair in a strong electric field, such as the vicinity of nucleus is called pair production.
OR
The process in which when high energetic photon having energy equal to or greater than 1.02 MeV, enters a very strong electric field, then this photon disintegrate in to positron and electron.
Explanation:-
This is a process in which photon loses its identity. When an attempt is made to stop a photon by a nucleus of a heavy material, it disintegrates in to an electron positron pair. A positron is a anti particle of electron or we can say that it is a positive electron. During the process of pair production energy, momentum and charge all are conserved. In order to conserve the momentum and energy, the pair production takes place near a nucleus which takes the recoil. This process is called the materialization of energy. Energy and mass are interchangeable according to the Einstein equation E = mc2. i hope you have understand the pair production if you have any confusion yet the please check this http://www.notes4all.com chapter modern physics page # 1 to 5. i have got also informative knowledge from this thanks
