  This paper presents part of an internal LANL Progress Report on completion of
the "S" and "G" versions of the improved Cascade-Exciton Model (CEM03.01) and
the Los Alamos Quark-Gluon String Model (LAQGSM.03.01) codes. The "S" versions
consider fragmentation of compound nuclei produced after the preequilibrium
stage of reactions for excitation energies above 2A MeV using the Statistical
Multifragmentation Model (SMM) by Botvina et al. ("S" stands for SMM), while
the "G" versions describe evaporation/fission stages of reactions using the
fission-like binary-decay model GEMINI of Charity et al. ("G" stands for
GEMINI) instead of using the the Generalized Evaporation Model GEM2 of Furihata
incorporated into the standard versions of these codes. We present here an
analysis of the recent 660 MeV p + 129I and 3.65 GeV p + 112Sn JINR
measurements, of the new COSY data on 1.2 GeV p + (13 nuclei from Al to Th), of
the 300 MeV and 1 GeV p + 56Fe data measured at GSI in inverse kinematics, and
of the new GSI data on 1 GeV/nucleon 124Xe and 136Xe + Pb. To better understand
the mechanisms of fragment production, we discuss several calculated but
not-yet-measured kinematic characteristics of products of these reactions,
which are predicted to be quite different by SMM, GEMINI, and GEM2. We find
these kinematic quantities to be potentially useful in differentiating these
reaction mechanisms if they can be measured in future experiments.
