Fission fragment angular distributions and yields of 236U in low-energy photofission

Abstract A measurement of the angular distribution and yield of fission fragments from photofission of 236 U has been performed between 5.2 MeV and 6.4 MeV. As γ-source the bremsstrahlung from a microtron has been used. For the detection of the fission fragments, solid-state track detectors were used. The experimental data were analyzed within the framework of the doublehump fission barrier model.
