On Scission Configuration in Ternary Fission
نویسنده
چکیده
A static scission configuration in cold ternary fission has been considered in the framework of two mean field approaches. The virial theorems has been suggested to investigate correlations in the phase space, starting from a kinetic equation. The inverse mean field method is applied to solve single-particle Schrödinger equation, instead of constrained selfconsistent Hartree–Fock equations. It is shown, that it is possible to simulate one-dimensional three-center system via inverse scattering method in the approximation of reflectless single-particle potentials.

Experimental data on angular distributions of γ rays emitted from binary and ternary spontaneous fission of 252 Cf are analyzed. Their difference indicates that the alignment of fragments is higher in ternary fission than in binary one. The consequences of possible relation between the mechanism of ternary fission and the excitation of collective modes during the saddle-to-scission stage are di...
متن کاملII-10 Pastina formation in low density nucleonic matter – a mechanism for ternary fission
Approximately 0.3 % of binary fission decays observed in the spontaneous or thermal neutron induced fission of a heavy nucleus are accompanied by emission of an energetic light particle or fragment in a direction perpendicular to the axis defined by the separating massive fragments. Considerable theoretical and experimental effort has been directed towards understanding this type of ternary fis...

Intermediate mass fragments ~IMFS! ~IMF: 3<Z IMF<20) observed in coincidence with two correlated fission fragments following incomplete fusion in C1Th at E/A516 and 22 MeV are investigated. IMFs emitted prior to significant deformation of the fissioning system, as well as IMFs emitted near scission, are distinguished based upon their characteristic kinetic energy and angular distributions. The ...

The cold(neutronless) fission of 252 Cf is studied in the frame of a molecular model in which the scission configuration is described by two aligned fragments interacting by means of Coulomb (+ nuclear) forces. The study is carried out for different distances between the fragments tips and excitation energies. For a given deformation, the fragment's total energy is computed via the constrained ...
