The production of electron-positron pairs by photons in the Coulomb field of electrons and positrons (triplet production) in hot thermal plasmas is investigated. The pair production rate for this process is calculated as a function of the photon energy and compared with the rate of photon-nucleus pair production for semirelativistic and relativistic plasma temperatures.
