Abstract

Data on cross sections for the reaction 238U(γ,F) in the giant-resonance region were analyzed in connection with the preparation of new experiments aimed at studying 238U photofission—in particular, in beams of photons from in-flight positron annihilation on internal targets of positron storage rings. These data were taken from measurements also performed with annihilation photons but from positron beams external to the accelerators used. The procedures applied in such measurements and based both on processing the multiplicity of detected neutrons and on detecting fission fragments were also analyzed.
