Abstract

Recent developments of the Cascade-Exciton Model (CEM) of nuclear reactions are briefly described. These changes are motivated by new data on isotope production measured recently in "reverse kinematics" at GSI for interactions of 208-Pb and 238-U at 1 GeV/nucleon and 197-Au at 800 MeV/nucleon with liquid 1-H. This study leads us to CEM2k, which is a new version of the CEM code that is still under development. The increased accuracy and predictive power of the code CEM2k are shown by several examples. Further necessary work is outlined.
