The experiment:
86 elastic Λ-nucleon events have been recorded in an exposure
of the Ecole Polytechnique Heavy Liquid Bubble Chamber at CERN to a beam of
stopping 1.47 GeV/c K- mesons. The liquid was freon.
20000 pictures have been scanned
The data:

Notes:
-
The results are based on the assumptions of charge symmetry
(elastic Λ p cross section equals elastic Λ n
cross section).
-
A rough estimate of the cross section for Λ p →
Σ0 n
is made. We do not include this.
