Fission of Uranium, Silver, and Bromine Nuclei with High-Energy Particles

Abstract

New data are presented on the high-energy fragmentation and fission of U, Ag, and Br in nuclear emulsions. The method of investigation is described.The nature of triple-pronged events involving fission of U with 560-660 Mev protons is discussed.Data are given concerning fission of U with 300-Mev ${\ensuremath{\pi}}^{+}$ mesons. The cross section for the fission of Ag with high-energy protons is determined.
