YN scattering data: ST61
The experiment:
Events have been seen in the 30-inch propane bubble chamber of the
Lawrence Radiation Laboratory.
200000 pictures were scanned.

Notes:
-
The article contains a table with characteristic properties of each
event.
-
Corrections for undetectable small angle scattering have been applied;
For Σ+ scattering an isotropic angular distribution
is assumed while
for Σ- scattering some peaking in the forward direction
is assumed.
