A reliable representation of the invariant cross section for the production of antiprotons in inclusive reactions is obtained, which fits the data extremely well from threshold to ISR energies. Using this representation, the production spectrum of antiprotons by cosmic ray interaction with interstellar gas is calculated and compared with other existing calculations. The antiproton equilibrium spectrum in the galaxy is derived from about 100 MeV to a few hundred GeV in kinetic energy using the Leaky Box Model for the propagation of cosmic rays by taking into account all energy loss processes. It is found that the antiproton/proton ratio calculated here is markedly smaller than the observed ratio. Since this excess of observed antiproton/proton ratio is much larger than the measured upper limits on the fraction of antimatter in the form of antinuclei, the excess antiproton/proton ratio is not attributed to the existence of antimatter. It is instead shown that the Closed Galaxy Model for the propagation of cosmic rays predicts more antiprotons than observed.
