Merging the CEM2k and LAQGSM Codes with GEMINI

An improved version of the Cascade‐Exciton Model (CEM) of nuclear reactions contained in the code CEM2k and the Los Alamos version of the Quark‐Gluon String Model (LAQGSM) are merged with the well‐known sequential‐binary‐decay model GEMINI by Charity. We present some results on proton‐induced fragmentation, fission‐product yields and on particle spectra predicted by these extended versions of CEM2k and LAQGSM. We show that merging CEM2k and LAQGSM with GEMINI allows us to describe many fission and fragmentation reactions in addition to the spallation and evaporation reactions which are already described well by these codes. Nevertheless, the current version of GEMINI merged with CEM2k and LAQGSM does not provide a completely satisfactory description of some complex‐particle spectra, fragment emission, and spallation yields for some reactions, and is not yet a universal tool for applications. Our results show that GEMINI contains a powerful model to describe evaporation/fission/fragmentation reactions and ...
