We present experimental results on measuring a single spin asymmetry in η-meson production in the interaction of transversely polarized protons and antiprotons at p1ab = 200 GeV/c with a proton target in the region 0.2 < XF < 0.7 for pp, 0.3 < XF < 0.7 for pp and 0.7 < PT 2.0 GeV/c. A comparison of single spin asymmetries in π- and η-meson production is made.
