Scientific paper

The production of secondary antiprotons in young supernova shells with an internal pulsar source of cosmic rays is calculated. The observed antiproton/proton ratio is explained by assuming that these sources produce 15-25 percent of all galactic cosmic rays. It is concluded that the model considered can explain the observed high integral flux of the antiprotons and their flat energy spectrum.
