  In peripheral high-energy heavy-ion collisions only parts of colliding nuclei
interact leading to the production of a fireball. The remnants of such nuclei
are called spectators. We estimated the excitation energy as a function of
impact parameter. Their excitation energy is of the order of 100 MeV. The
dynamical evolution of hot nuclei is described by solving a set of Langevin
equations in four-dimensional collective coordinate space. The range of nuclear
masses and excitation energies suits very well to ability of our model. Thus
for the first time we investigate dynamically the fission and evaporation
channels in de-excitation of the spectators produced in heavy-ions collision.
