NUCLEAR DEFORMATION IN FISSION FRAGMENTS STUDIED WITH NOVEL IMPLEMENTATIONS OF DOPPLER SHIFT LIFETIME MEASUREMENT TECHNIQUES
… measurement of lifetimes of excited states in fission fragments. This method has been applied to the first set of data taken with an active fis- sion target coupled to an array of germanium detectors. The nuclei have been populated via neutron-induced fission on 235 U, dissolved in a liquid …

The effect of radiation damage by fission fragments on the structural stability and dissolution of the UO2 fuel matrix
… of this work was to study the separate effect of fission fragment damage on the structural integrity and matrix dissolution of uranium dioxide in water. Radiation damage similar to fission damage was created by irradiating bulk undoped and doped ‘SIMFUEL’ disks of UO2, undoped bulk CeO2 and thin …

Molecular dynamic simulation of xenon bubble re-solution in uranium dioxide
… is a comprehensive study of two mechanisms of fission gas bubble re-solution in UO2 by molecular dynamics (MD) simulations: homogeneous re-solution and heterogeneous re-solution. For the homogeneous mechanism, a hybrid approach is employed whereby Monte Carlo (MC) simulations are used to obtain …

Energy correlations of prompt neutrons from 252Cf fission
… coincident neutrons emitted in the spontaneous fission of ²⁵²Cf. The hypothesis that cooling of the fission fragments during the cascade evaporation of prompt neutrons affects the energies of successive neutrons in a cascade has been investigated by a comparison of the energy correlations of …

An ionization chamber for fission fragment analysis
Fission fragments play a pivotal role in understanding the entire nuclear fission process, and their effects are widespread to all applications involving nuclear fission: reactor design and maintenance, waste removal, active and passive integration of nuclear materials, simulations, and the …

Study of transverse excitations in the giant resonance region of 236U using the (e,e'f) reaction.
… was possible. The data were integrated over the fission angle and compared with the calculations using both the Tassie model and the QRPA form factors. At the two lowest momentum transfers the data are well described by the inclusion of the electric multipoles of L = 0, 1, 2 and 3 transitions. …

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 …
