“…Some of the most important results coming from LEAR are the high-quality elastic analyzing-power A y (polarization) data, measured by the PS172 [122,123] and PS198 [130,120] collaborations at a number of energies above 439 MeV/c. Since in the pre-LEAR era only very few and inaccurate data points existed [132,127,131], these experiments mean real progress. We find the data of PS172 and PS198 to be consistent, except for their normalizations.…”

A partial-wave analysis of all antiproton-proton scattering data below 925 MeV/c antiproton laboratory momentum is presented. The method used is adapted from the Nijmegen phase-shift analyses of pp and np scattering data. The Nijmegen 1993 antiproton-proton database, consisting of 3646 antiproton-proton scattering data, is presented and discussed. The best fit to this database results in chi^2_min/Ndata = 1.043. The pseudovector coupling constant of the charged pion to nucleons is determined to be (f_c)^2 = 0.0732(11) at the pion pole, where the error is statistical.Comment: Report THEF-NYM 93.02 42 pages REVTeX, 7 separate postscript figures appended.
