The analysis of nuclear interactions of protons in photoemulsion showed that the mean proton path at 1 to 9 Bev varies very little. The mean path of a 9- Bev proton was found to equal 34.7 plus or minus 1.5 cm; the mean number of fast particles formed in single interactions was 3.4 plus or minus 0.1. The angular distribution of fast particles in laboratory coordinates and the distribution of the stars produced are shown graphically. From an analysis of 249 stars, eighteen were considered as cases of interactions with free or quasi- free protons. Thirteen stars were considered as proton interactions with quasi- free neutrons. The mean number of fast particles in such stars was 3.1 plus or minus 0.3. The tracks of all fast particles were examined until they left the emulsion or underwent a second collision. Ten secondary stars were faund. The mean path for the secondary particles was 19 plus or minus 6 cm. (R.V.J.)
