  We present the current status of the improved Cascade-Exciton Model (CEM)
code CEM2k and of the Los Alamos version of the Quark-Gluon String Model code
LAQGSM. To describe fission and light-fragment (heavier than He4) production,
both CEM2k and LAQGSM have been merged with the GEM2 code of Furihata. We
present some results on proton- and deuteron-induced spallation, fission, and
fragmentation reactions predicted by these extended versions of CEM2k and
LAQGSM. We show that merging CEM2k and LAQGSM with GEM2 allows us to describe
many fission and fragmentation reactions in addition to the spallation
reactions which are already relatively well described. Nevertheless, the
standard version of GEM2 does not provide a completely satisfactory description
of complex particle spectra, heavy-fragment emission, and spallation yields,
and is not yet a reliable tool for applications. We conclude that we may choose
to use a model similar to the GEM2 approach in our codes, but it must be
significantly extended and further improved. We observe that it is not
sufficient to analyze only A and Z distributions of the product yields when
evaluating this type of model, as is often done in the literature; instead it
is important to study all the separate isotopic yields as well as the spectra
of light particles and fragments.
