Abstract
For the first time we have explored the effects of the magnetic field in a nova shell on the escape of positrons from the radioactive isotope \({}^{22}\)Na and on the evolution of the flux in the 511 keV annihilation line. We show that for a white dwarf surface magnetic field \({\sim}10^{6}\) G the magnetic field in an expanding nova shell is able to significantly impede the positron escape and to increase the emission time in the 511 keV line to hundreds of days.
