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…
Energy losses of 252Cf fission fragments in thin foils
2006
Abstract The stopping power of fission fragments from 252Cf(sf) has been measured in thin foils of C, Ni, Au, Al2O3 and Mylar as a function of fragment mass and energy. The chosen stopping materials are frequently used as the backing of sources and targets or entrance windows of gas detectors. The experimental setup allowed registration of velocities of two fission fragments and energy of one of them. In this way fragment masses could be unambiguously determined and the pulse-height defect of the silicon detector verified. The measured stopping power data for fission fragments cover masses between A = 101 and A = 148. The results are compared with semi-empirical predictions of SRIM 2003 cod…
