    "abstract": "The improved Cascade-Exciton Model (CEM) code CEM2k+GEM2 and the Los Alamos\nversion of the Quark-Gluon String Model code LAQGSM are extended to describe\nphotonuclear reactions. First, we incorporate into CEM2k+GEM2 new evaluations\nof elementary cross sections based on the latest experimental data and also\nmake several improvements in the description of the de-excitation of nuclei\nremaining after the cascade stage of reactions induced by arbitrary\nprojectiles. Next, for photonuclear reactions we include in CEM2k+GEM2 a\nnormalization to evaluated experimental absorption cross sections based on the\nrecent systematics by Kossov. Then, we extend our high-energy code LAQGSM by\nadding the photonuclear mode which was ignored in all its previous versions,\nand add to it the photonuclear part from our improved CEM2k+GEM2. In this work\nwe present a short description of the photonuclear mode as incorporated into\nour codes, show several illustrative results, and point out some unresolved\nproblems.",
