A search for heavy mesons decaying to pp¯, pp¯π ..., KK¯, KK¯π ... and Kπ, Kππ… in 9 GeV/c antiproton-proton reactions has been made. Based on a sample of 9514 events with pp¯ and 139 events with KK¯, no evidence for masses in the region 1–4 GeV/c2 was found. The inclusive strange particle cross sections were estimated to be σλ0) = 0.65 ± 0.05 mb and σKS0 = 1.20 ± 0.07 mb.
