摘要：

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 superconducting 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. First experiments on U-238 and U-234 have shown that the experimental setup provides excellent conditions for investigating low-energy bremsstrahlung induced fission. Further experiments on U-234 and Th-232 are currently in progress. In this contribution results from the first experiment on fission fragment mass and total kinetic energy distributions from U-234,U-238 are presented along with preliminary data from an on-going investigation of angular distributions from U-234(gamma, f).
