Abstract
This paper, which is a continuation of Paper I (Zheleznyakov and Litvinchuk, 1985), studies the formation of a one-quantum annihilation line in the spectrum of gamma-ray bursts. The radiative transfer equation together with the positron density balance relation is solved, and the expected photon fluxes in the one- and two-quantum annihilation lines are calculated. The fractional luminosities of these lines versus source parameters are investigated. For a gamma-burst one-photon annihilation line, the luminosity is always much less than that for the two-photon line-i.e., the positron source power transforms almost entirely into radiation in the two-quantum annihilation line and the positron density depends solely on the specific source power and two-quantum annihilation probability. The flux of one-quantum annihilation quanta 1 MeV is estimated to be less than what modern detectors can resolve. This explains failure to detect the one-photon annihilation lines in gamma-bursts so far.
