Summary:
The total cross section for the reaction K/sup -/p ..-->.. anti K/sup 0/n was measured between 500 and 1050 MeV/c in steps of 10 MeV/c. The experiment was performed at the Brookhaven AGS using a negative kaon beam focused onto a 41 cm long liquid hydrogen target. The target was surrounded by a box of scintillation counters which detected and vetoed all charged final states. The charged particle veto box was in turn surrounded by a box of lead-scintillator sandwich shower counters. These counters detected and vetoed all final states with photons or ..pi../sup 0/'s. The only reaction left unvetoed was K/sup -/p ..-->.. K/sub L/n, the cross section for which is just /sup 1///sub 2/ the K/sup -/p ..-->.. K/sub L/n, cross section. It was necessary to make a number of corrections to the data to account for event losses and inefficient background rejection. The final results have a statistical accuracy of 1% which is an improvement of almost a factor of 10 over previously existing data. An important new feature can be seen in the cross section, a significant shoulder between 825 and 900 MeV/c. Preliminary results from a partial wave analysis including the new data indicate that the new cross sections will be an important constraint on future analyses.
