Delayed neutron yields and spectra from photofission of actinides with bremsstrahlung photons below 20 MeV.

Experimental results for the photofission of ²³⁸U with an endpoint Bremsstrahlung emission of 15 MeV are presented. Absolute yield and time characteristics of the delayed neutrons are extracted. In parallel, calculations for fission fragment distributions and corresponding delayed neutron parameters are given and compared to data.
