"WebElectron-Positron Pair Production When a photon has quantum energy higher than the rest energy of an electron plus a positron, one of the ways such as a photon interacts with matter is by producing an electron-positron pair in the field of nucleus. This process cannot take place in free space because of the conservation laws violation. " - How is a positron similar to the electron
