The characteristics of stars produced by collisions of E/sub p/ = 27 Bev protons on emulsion nuclei are studied. Multiplicities n/sub s/ = 6.6 plus or minus 0.1 and n/sub h/ = 7.2 plus or minus 0.2 are obtained. The mean energy of the secondary shower particles is 2.3 plus or minus 0.2 Bev. The energy transfer to the secondary mesons in the 1. s. is K approximately 0.6 E/sub p/. From the angular distribution, the mean number of collisions inside the nucleus is found to be 1.1 and and 2.7 for light and heavy nuclei respectively. The mean free path (mfp) for absorption is lambda = 38.0 plus or minus 1.0 cm which, according to an optical model, corresponds to a nuclear mfp lambda /sup n/ = (4.3 plus or minus 0.3) fermi. (auth)
