The experiment:
238 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.
10.000 frames were scanned, 256 events were found of which 238 were
accepted for the final analysis.
The presented results were `preliminary'; the final results
are presented in AL68
