  The improved Cascade-Exciton Model code CEM2k and the Los Alamos version of
the Quark-Gluon String Model code LAQGSM, previously merged with the
Generalized Evaporation Model code of Furihata (GEM2) were further modified to
provide reliable proton-induced fission cross sections for applications. By
adjusting two parameters in GEM2 for each measured reaction, we were able to
describe very well with CEM2k+GEM2 and LAQGSM+GEM2 all available experimental
fission cross sections induced by protons with energies from 20 MeV to 10 GeV
both for subactinide and actinide targets. We also successfully tested our
approach on several reactions induced by neutrons, pions, and photons.
