Measurement of the prompt fission y -rays from slow neutron-induced fission of 235 U with STEFF

The average energy and multiplicity of prompt y -rays from slow neutron-induced fission of 235 U have been measured using the STEFF spectrometer at the neutron time-of-flight facility n_TOF. The individual responses from 11 NaI scintillators were corrected for multiple y -ray interactions, prompt fi...
