Scientific paper
The emission of positrons from supernova ejecta was discussed in terms of the galactic center annihilation radiation. The positrons from the radioactive sequences (56)Ni(FEMADE) (56)Co(FEMADE) (56) Fe are the most numerous source from supernova. Only type 1 supenova allows a significant fraction to escape the expanding ejecta. For a neutron star model of a type 1 SN a fraction 4 x 10(+3) of the escape positron is enough to create the observed several year fluctuation of the annihilation radiation. The likelihood of this model in terms of other astrophysical evidence and the type 1 SN light curve are discussed.
