Fragment properties from fission of ^234,238U induced by 6 -10 MeV bremsstrahlung — •Alf Göök¹, Christian Eckardt¹, Joachim Enders¹, Martin Freudenberger¹, Franz-Josef Hambsch², Peter von Neumann-Cosel¹, Andreas Oberstedt^3,4, Stephan Oberstedt², and Achim Richter^1,5 — ¹Institut für Kernphysik, Technische Universität Darmstadt, Germany — ²EC-JRC IRMM, Geel, Belgium — ³Akademin för Naturvetenskap och Teknik, Örebro Universitet, Sweden — ⁴Fundamental Fysik, Chalmers Tekniska Högskola, Göteborg, Sweden — ⁵ECT*, Villazzano (Trento), Italy

Experiments to investigate the photon-induced fission of actinide nuclei at excitation energies in the vicinity of the fission barrier are carried out at the super conducting Darmstadt linear electron accelerator S-DALINAC. A twin Frisch grid ionization chamber is used to deduce mass, total kinetic energy, and angular distributions of the fission fragments. In this contribution results on fission fragment mass and total kinetic energy distributions from ^234,238U will be presented along with the currently on-going investigation of ²³⁴U and ²³²Th fragment angular distributions.
