We are not aware of any paper devoted to the theoretical or experimental study of the
spin transfer mechanism from the polarized protons to the inclusively produced at zero
degree antiprotons. Basing on the several experimental data on the spin-transfer effect
in elastic and inclusive reactions for protons and lambda hyperons we hope that similar
effect may exist also for antiprotons. We would like to emphasize the importance to fulfill
the special experiment for measuring the polarization transfer tensor KLL in reaction
p(→)+A = p(→)+X at AGS. Initial proton beam with momentum around 22 GeV/c,
longitudinal polarization 70%, intensity 210 11 p/cycle, may produces the longitudinally
polarized p beam at zero degree. Our estimates show that though such an experiment is
difficult but it is realizable.
