The experiment:
The reactions Λ p → Λ p and
Λ p → Σ0 p
have been examined in a sample of 5000 Λ particles produced in the
Alvarez 72-inch hydrogen bubble chamber.

Notes:
-
Small angle Λ scattering events could not be detected. Corrections
to the cross section have been applied for this.
-
The article contains a table with characteristic properties of each
event.
