The experiment:

75 elastic Λ p events have been recorded in an exposure of the Saclay 81 cm hydrogen bubble chamber at CERN to a beam of stopping K- mesons.
These results were preliminary; final results are published in SE68.

The data:

Λ p → Λ p total elastic cross section (SGT)
momentum range   effective mean     number of    SGT [mb]
    [MeV/c]     momentum [MeV/c]     events

  120 - 170          144               10     130 +/- 50
  170 - 200          186               11     105 +/- 34
