Pair production from hot plasma in the presence of a strong magnetic field

Abstract

Radiation loss due to pair production by ah intense electromagnetic wave is calculated. The calculations were made in the coulomb field of the ions and in the presence of a constant strong magnetic field aligned along the z-direction. The expression obtained for the radiation loss can be used for the case of nonrelativistic electrons and positrons. These calculations may be of great importarLce for the astrophysical estimations, since the basic mechanism of the energetic losses is mainly due to pair production.
