We are very grateful to Prof.J. E. Lofgren and his collaborators for the exposure of the stack. Our thanks are also due to the Bristol group for the processing of the plates and to the colleagues of Bristol, Dublin U.C., U.C.L.A. and B.N.L. who kindly supplied their data previous to publication.
We have calculated thep T distribution to be expected for K-bound proton collision (Fermi model;p max = 241 MeV/c). From this distribution and from the total number of two prong scatterings, we have calculated that the contamination in our K-H sample is less than 0.5 event. Further details and results will be given at the Geneva Conference.
Λ1 is the m.f.p. corrected for Coulomb effect.
