Superfluorescent decay in quasiballistic disordered systems
  Superfluorescent decay in a weakly disordered slab is considered. By solving the Maxwell-Bloch equations we show, that the cooperation number increases with increasing of the mean free path. Superfluorescent impulse is emitted at a small angle to the slab, isotropically in a plane direction.
