Scientific paper

The formation mechanism of an annihilation line 0.5 MeV in gamma-ray bursts due to electron-positron pair production in strong magnetic fields of neutron stars is discussed. Positron production due to isotope decay and due to nu-meson production is considered. It is shown that a large part of radiation with the energy E greater than 2mc-squared per quantum is consumed by pair production and does not escape from the gamma bursts, which indicates a possible strong gap in continuum radiation at energies higher than 1 MeV. The expected annihilation line intensity in gamma-ray burst spectra is estimated, and agrees with observational data.
