摘要：

From approximately 12 000 four-prong annihilations of 1.2 GeV/c antiprotons in hydrogen about 200 events involving two charged kaons were selected mainly on basis of ionization. The cross sections for the K+K-π+π- and K+K-π+π-π0 final states are 260 ± 40 μb and 290-60+40 μb, respectively. The amounts of resonances produced have been estimated. The four-body final state is dominated by K*(890) production, whereas the five-body final state shows an abundant production of K*(890), ω(783) and ø(1019). © 1969.
