Scientific paper

The authors assume that SN II and SN Ib are the sources of γ-ray lines, and that they produce a large amount of 26Al diffused in the interstellar medium as a result of explosive nucleosynthesis; they also consider that stars have different mass and space distributioin in the Galaxy, and put the explosive rates of SN as limits to total mass of stars in the Galaxy. The authors have calculated and discussed the radiant fluxes of γ-rays line of several nuclides. The calculation shows that SN II and SN Ib a probably the major sources of 26Al, but its models about 44Ti meed to be modified.
