Analysis of Spallation and Fission Residues for Separated Lead Isotopes Irradiated by Protons at Energies 0.15, 1.0, and 2.6 GeV

Spallation and fission residues produced by the proton irradiation of 206Pb, 207Pb, and 208Pb targets at energies from 0.15 up to 2.6 GeV have been studied recently at ITEP. These data allow testing various versions of the intranuclear cascade models widely used for simulation of spallation product yields. The main differences between codes are briefly reviewed. Modifications of the LAHET and CASCADO codes, which are required to reduce the deviations from experimental data, are discussed.
