  We have studied the fragment yields emitted from the fragmentation of excited
projectile nuclei in peripheral collisions of 136Xe+Pb at 1 GeV/nucleon, and
measured with the high-resolution magnetic spectrometer, the Fragment Separator
(FRS) of GSI. The mass, charge and isotope distributions of nuclear fragments
formed in the reactions were calculated within a statistical ensemble approach
and compared to the experimental data. The ensemble of excited projectilelike
source nuclei were created in the framework of a previous analysis of similar
reactions performed at 600 MeV/nucleon (ALADIN-experiments, GSI). The overall
agreement between theory and experiment was very satisfactory in reproducing
the experimental data of isotope yields measured in the heavy-ion collisions.
It is seen that a broad range of isotopes of the elements between Z=3 and Z=54
(near-projectile isotopes) can be reproduced from fragmentation of 136Xe
projectiles.
