Query: Microscopic description of proton-induced spallation reactions with the
  Constrained Molecular Dynamics (CoMD) Model   We studied the complete dynamics of the proton-induced spallation process
with the microscopic framework of the Constrained Molecular Dynamics (CoMD)
Model. We performed calculations of proton-induced spallation reactions on
181Ta, 208Pb, and 238U targets with the CoMD model and compared the results
with a standard two-step approach based on an intranuclear cascade model (INC)
followed by a statistical deexcitation model. The calculations were also
compared with recent experimental data from the literature. Our calculations
showed an overall satisfactory agreement with the experimental data and suggest
further improvements in the models. We point out that this CoMD study
represents the first complete dynamical description of spallation reactions
with a microscopic N-body approach and may lead to advancements in the
physics-based modelling of the spallation process.
