摘要：

Data are presented for the reaction K-d→Λπ-p at 910, 1007, and 1106 MeV/c in which the proton momentum is greater than 250 MeV/c. The Λp invariant-mass plot shows an enhancement at about 2130 MeV, similar to that found by Cline, Laumann, and Mapp. No enhancement is seen at about 1440 MeV in the Λπ invariant mass. A simple two-step process describes our data as well as those of Cline, Laumann, and Mapp without the use of resonances. © 1969 The American Physical Society.
