Particular features of ternary fission induced by polarized neutrons in the major actinidesU233,235andPu239,241
2016
Ternary fission in $(n,f)$ reactions was studied with polarized neutrons for the isotopes $^{233,235}\mathrm{U}$ and $^{239,241}\mathrm{Pu}$. A cold longitudinally polarized neutron beam was available at the High Flux Reactor of the Institut Laue-Langevin in Grenoble, France. The beam was hitting the fissile targets mounted at the center of a reaction chamber. Detectors for fission fragments and ternary particles were installed in a plane perpendicular to the beam. In earlier work it was discovered that the angular correlations between neutron spin and the momenta of fragments and ternary particles were very different for $^{233}\mathrm{U}$ or $^{235}\mathrm{U}$. These correlations could no…
QUATERNARY FISSION
2003
Quaternary fission is a nuclear reaction where the two customary fragments from fission are accompanied by two light charged particles. The process has been investigated at the ILL, Grenoble, for thermal neutron induced fission of 233U and 235U. The light particles were identified to be α particles and H isotopes (mostly tritons). Two different types of processes could be disentangled: in one of these processes all four charged particles are born in coincidence while the second process is in fact merely a special case of ternary fission where the ternary particle decays into two charged particles before reaching the detectors.

CORRELATIONS IN TERNARY FISSION
2000
An experiment investigating correlations in ternary fission of233U induced by cold polarized neutrons was performed at the high flux reactor of the ILL in Grenoble (France). With the experimental setup, Left—Right and time reversal symmetry violating and conserving correlations between neutron spin\(\hat \sigma \), neutron momentum\(\hat p_n \), momenta of fission fragments\(\hat p_f \) and ternary particles\(\hat p_t \) could be investigated.
