摘要：
Photonuclear reactions, especially photofission delayed neutron emission, play an important role for applications involving nuclear material detection. In order to provide good quality data for evaluations and data libraries, an experimental program of delayed neutron measurements has been undertaken for actinides with Bremsstrahlung energy from 12 up to 20 MeV. In this paper, we report on delayed neutron yields and time spectra characteristics from the photofission of U-238 and U-235 for several endpoint energies between 12 and 18.5 MeV. The associated modelling efforts will be described including some calculations compared to experimental data.
