It is possible for a photon to materialize into an electron and a position. The process is called pair production.
(a) Using conservation of energy and momentum prove that pair production cannot occur in empty space.
(b) Argue qualitatively that such pair production is possible near a nucleus.

gamma-rays radiation can be used to create electron-positron pair. In this process of pair production. gamma-rays energy cannot be less than.

Statement-I : Coversionof a gamma photon into an electron and a positron is an example of pair production. Statement -II : Pair production refers to the creation of an elementary particle and its antiparticle,usually when a photon interacts with a nucleus.

For pair production i.e. for the production of electron and positron, the incident photon must have a minimum frequency of the order of

The passage of gamma -rays photons through materials sometimes results in pair production, i.e., the transformation of a gamma -rays photon into a positron and an electron (eachof mass m). What is the maximum wavelength of gamma - ray photons for which pair production is possible? (c = speed of light, h = plank constant)

Energy of each photon obtained in the pair production process will be if the mass of electron or positron is 1/2000 a.m.u-
