  The improved Cascade-Exciton Model (CEM) code CEM2k+GEM2 and the Los Alamos
version of the Quark-Gluon String Model code LAQGSM are extended to describe
photonuclear reactions. First, we incorporate into CEM2k+GEM2 new evaluations
of elementary cross sections based on the latest experimental data and also
make several improvements in the description of the de-excitation of nuclei
remaining after the cascade stage of reactions induced by arbitrary
projectiles. Next, for photonuclear reactions we include in CEM2k+GEM2 a
normalization to evaluated experimental absorption cross sections based on the
recent systematics by Kossov. Then, we extend our high-energy code LAQGSM by
adding the photonuclear mode which was ignored in all its previous versions,
and add to it the photonuclear part from our improved CEM2k+GEM2. In this work
we present a short description of the photonuclear mode as incorporated into
our codes, show several illustrative results, and point out some unresolved
problems.
