Ten examples of the protonic decay from rest of the hyperon have been analyzed. The ranges of the protons from the decays were corrected for variations in the stopping power of each emulsion batch by determining the mean range of mesons from decays. The mean range of the protons, after correcting for variations in stopping power, was found to be 1669.4±8.0 microns. The rms deviation of the proton ranges was found to be 38.5±8.0 microns. The of the decay, is 116.1±0.5 Mev, and the mass of the hyperon is .
