Question

What is meant by the pair production? Explain with the help of an example and a balanced equation.

Answer 1

Pair production is the creation of an elementary particle antrparticle from a neutron boron. Examples include creating an electron and a proton, a muon and an anti muon or a proton or an anti proton. Pair production often refers specifically to a proton creating an electron proton pair near a nucleus. In order for pair production to occur, the incoming energy of the interaction must be above the threshold in order to create the pair at least the total rest mass energy of the two particles and that situation allows both energy and momentum to be conserved. However all other conserved quantum numbers of the produced particles must sum to zero thus created particles shall have opposite values of each other. For instances, if one particle has electric charge of +1 and the other must have electric charge of - 1.
