FISSION FRAGMENT PROPERTIES OF 235-U(N,F) IN THE NEUTRON ENERGY RANGE FROM THERMAL TO 1 MEV
The fission fragment energies and emission angles of both fragments have been measured for 235-U(n,f) in the neutron energy range from thermal to 1 MeV. The experimental detection technique used together with the pulsed white neutron source GELINA is described. The fission fragment angular anisotropies show, in agreement with earlier measurements, negative values below 0.3 MeV. This leads to the conclusion, that either R- (eigenvalue r = +1) or S- (s = +1) invariance of the fissioning system at the saddle is fulfilled. The average total kinetic energy shows structure in the resolved resonance neutron energy region below 120 eV. This structure is anticorrelated with nu-p(E), the average number of prompt fission neutrons. The average total kinetic energy changes are mass dependent.
