YN scattering data: CL67

Authors: D. Cline, R. March, M. Sheaff
Reference: Phys. Lett. 25B (1967), 446
Group: Madison

The experiment:

Elastic Λ p events have been recorded in an exposure of the LRL 25-inch bubble chamber to a K- beam at the Bevatron. The chamber was filled both with hydrogen and deuterium. 78 elastic events have been recorded.

The data:
