Characteristics of light charged particle emission in spontaneous and neutron induced fission of Cm and Cf isotopes
Talking about fission, people think almost automatically about a nucleus that splits into two heavy pieces. However, in 1946 the phenomenon of ternary fission has been discovered, in which the two fission fragments are accompanied by a light charged particle. Ternary fission data are of interest …

Fission fragment mass distributions and total kinetic energy release of 235-uranium and 238-uranium in neutron-induced fission at intermediate and fast neutron energies LA-UR-15-28829
… release with increasing incident neutron energy for fission of $^{235}$U and $^{238}$U. Although fission was discovered over seventy-five years ago, open questions remain about the physics of the fission process. The energy of the incident neutron, $E_n$, changes the division of …

Prompt neutrons from fission of 252Cf and 235U
… been made of the n-n angular correlation for neutrons emitted in spontaneous fission of ²⁵²Cf and thermal-neutron- induced fission of ²³⁵U. The dependence of the angular correlation on the neutron detection threshold energy was investigated. These measurements and other experimental data on …

NUCLEAR DEFORMATION IN FISSION FRAGMENTS STUDIED WITH NOVEL IMPLEMENTATIONS OF DOPPLER SHIFT LIFETIME MEASUREMENT TECHNIQUES
… techniques. In this Thesis, the deformation of neutron-rich nuclei with mass A≈100 has been in- vestigated at medium-high spin (8-10ħ) by measuring the lifetime of excited states to determine transition strengths, from which the size of the deformation can be inferred. Particular focus has been …

Measurement of neutron production from an ¹⁸O target for the production of radioactive-ion beams at iThemba LABS
… proposes to produce radioactive ion beams by the fission of uranium. A natural way to fission uranium is to use high-intensity proton beams from a cyclotron. However, neutron-induced fission gives enhanced production of neutron-rich fission fragments compared to proton-induced fission, thus there …
