Study of nuclear fragment emission from targets bombarded by intermediate-energy protons

The nuclear fragment registration by 6-μm lavsan film detectors was studied in experiments with a 0.2-4 GeV proton beam. The targets from Be to Pb were used in these measurements. Only the nuclear fragments with large local energy deposition and Z>5 produced in reactions of spallation, fragmentation and fission were detected. The dependence of the number of the registered secondary nuclei on the energy of incident protons and mass number of the target nuclei is discussed
