Measurements and analysis of the distributions of the uranium nucleus fission rates in lead and uranium targets under action of 1.3 and 4.3 GeV protons

Experiments on 1.3 and 4.3 GeV energy proton beams, bombarding the targets of lead and depleted uranium are described. The fission rates are measured by the solid-state track detectors. The experimental distributions are compared with the Monte Carlo simulation results. The agreement of the measurements with the calculations is satisfactory for 1.3 GeV protons. An appreciable difference between experiments and calculations is observed at 4.3 GeV beam energy. 9 refs.; 6 figs.; 2 tabs
