Abstract: 

Dipole excitations in fission fragments at the scission point have been studied in a classical model. These excitations correspond to a density fluctuation caused by the Coulomb repulsion between the fragments. A simple two-sphere approximation to the scission configuration is used for these studies. The dipole density distribution is obtained from a hydrodynamic picture of the fragment nucleus and the dipole amplitude parameters are fixed by minimizing the total potential energy at the scission point. Calculations have been made for the symmetric and asymmetric scission configurations corresponding to the fission of ²³⁵U by thermal neutrons. The dipole excitation energy is found to be about 0.5 MeV in one fragment and at the same time, the total energy is lowered by 1 MeV from its value calculated with a uniform density distribution.
