متن کاملFour Channels in the Fission of 252Cf
Strutinsky-type calculations indicate that the potential energy favors four channels in the nuclear fission of 252Cf. The connection of this finding with experimental results on the dis tribution of fragment mass, total kinetic energy, neutron multiplicities, and relative abundances is discussed. Similar calculations for 227Ac, 236U, and 258Fm show that the changing preponder ance of the four...
متن کاملTagging fast neutrons from a 252Cf fission-fragment source.
Coincidence and time-of-flight measurement techniques are employed to tag fission neutrons emitted from a 252Cf source sealed on one side with a very thin layer of Au. The source is positioned within a gaseous 4He scintillator detector. Together with α particles, both light and heavy fission fragments pass through the thin layer of Au and are detected. The fragments enable the corresponding fis...
متن کاملOn Scission Configuration in Ternary Fission
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 ...
متن کاملComparison of relative quasi-molecular ion yields for 8-keV ion and 252Cf fission fragment bombardment.
related to the relatively small number of total ions utilized for determining the mass spectra. CONCLUSION It would be a significant advance if the mass resolution of 1500 obtained with inorganic specimens could be retained with nonvolatile and thermally labile organic specimens as well as obtaining the structurally significant fragment ion signals. This advance will require more detailed studi...
