Going beyond the framework of the fixed nuclei (Born-Oppenheimer) approximation, we have addressed several questions related to the competition between excitation, dissociation, and ionization. In this context, it is shown that semiclassical simulations can provide valuable informations about the dynamics of the processes considered.}, year = {2006}, journal = {PHYSICAL REVIEW A}, volume = {73}, number = {6}, month = {JUN}, issn = {1050-2947}, doi = {10.1103/PhysRevA.73.063411}, }
