Tagging 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...

Tagging fast neutrons from an (241)Am/(9)Be source.

Shielding, coincidence, and time-of-flight measurement techniques are employed to tag fast neutrons emitted from an (241)Am/(9)Be source resulting in a continuous polychromatic energy-tagged beam of neutrons with energies up to 7MeV. The measured energy structure of the beam agrees qualitatively with both previous measurements and theoretical calculations.

0 Molecular Collective Vibrations in the Ternary Neutronless Fission of 252 Cf Ş

Based on a recent experimental finding which may suggest the existence of a tri-nuclear molecular structure before the cold ternary fragmentation of 252Cf takes place, we solved the eigenvalue problem of a certain class of vibrations which are very likely to occur in these molecules. These oscillations are the result of the joined action of rotations of the heavier fragments and the transversal...

Precision Mass Measurements of Heavy 252 Cf Fission Fragments Near the r - process Path

The path of the astrophysical r process and the resulting elemental distribution are dependent on the neutron-separation energies of species far from stability. The mass models used to extrapolate these energies have increasing uncertainties with neutron number. Therefore, precision mass measurements of species near the r-process path are vital to generate more precise predictions of elemental ...

Molecular vibrational states in the binary cold fission of 252 Cf

We predict a molecular vibrational state in the cold binary fission of 252 Cf using a simple decay cluster model. The Hamiltonian of two even-even fragments in the pole-pole configuration is built in the same fashion as that for the dinuclear molecule formed in heavy-ions collisions. The interaction between the two fragments is described by the double-folding M3Y potential. The spectrum of the ...
