The predictive power of spallation models for isotopic cross sections

The experimental cross sections of isotopically identified products of spallation reactions induced by 136Xe projectiles at 1GeV/nucleon on hydrogen target were compared with predictions of a two-step model. The first stage of the reaction was described by the INCL++ model (version 5.3) of an intranuclear cascade of nucleon-nucleon and pion-nucleon collisions whereas the second stage was analyzed by means of four different models; ABLA07, GEM2, GEMINI ++ and SMM. Due to the fact that the experimental data cover a very broad range of elements; from Li$(Z=3)$ to Ba$(Z=56)$ , the analysis could impose severe constraints on the applied reaction models. The quality of data reproduction by the theoretical models is discussed. Some systematic deviations of the theoretical predictions from the experimental results are observed
