It is shown that photons of the prolonged emission recorded by the GROWTH (Gamma-Ray Observation of Winter Thunderclouds) experiment on January 13, 2012 could be emitted by ball lightning and generated by annihilation of positrons which arose mainly due to production of the β⁺-active isotopes by the sharp γ-ray flash, accompanying the formation of ball lightning, and production of electron-positron pairs by photons from ball lightning. The model of ball lightning is based on the assumption that ball lightning has a core consisting of clouds of electrons and almost totally ionized ions which oscillate with respect to each other.
