    "abstract": "In Fermionic Molecular Dynamics the occurrence of multifragmentation depends\nstrongly on the intrinsic structure of the many-body state. Slater determinants\nwith narrow single-particle states and a cluster substructure show\nmultifragmentation in heavy-ion collisions while those with broad wave\nfunctions, which resemble more a shell-model picture, deexcite by particle\nemission. Which of the two type of states occurs as the ground state minimum or\nas a local minimum in the energy depends on the effective interaction. Both may\nequally well reproduce binding energy and radii of nuclei. This ambiguity led\nus to reinvestigate the derivation of the effective interaction from realistic\nnucleon-nucleon potentials by means of a unitary correlation operator which is\nmuch more suited for dynamical calculations than the G-matrix or the Jastrow\nmethod. First results of mixing many Slater determinants are also presented.",
