Abstract
A measurement of the angular distribution and yield of fission fragments from photofission of238U has been performed between 5.2 MeV and 6.4 MeV. Asγ-source the bremsstrahlung from a microtron has been used. For the detection of the fission fragments, solid state track detectors were used. The yield data were evaluated to approximate cross sections. The data were analyzed within the framework of the double hump barrier model.
