Benchmarking photoneutron production of Mcnpx simulations with experimental results
Accelerator driven subcritical systems (ADS) are one of the most viable methods for the transmutation and effective utilization of nuclear fuel. An important aspect of coupling the accelerator to a nuclear reactor is the generation of a high-energy neutron flux. The neutron flux can be generated by …

Photoneutron spectra from monoenergetic photons on Pb208 in the giant resonance
The time-of-flight of photoneutrons from Pb208 was observed at 1150 for incident gamma ray energies of 9.90 MeV to 16.87 MeV. The University of Illinois 25 MeV betatron and bremsstrahlung monochromator facility were used to produce the gammas and determine their energies within 1.7% (full width). …

Investigation of the photoneutron cross section in 206Pb and 208 Pb from 9 to 16 MeV
The time of flight of photoneutrons from 206Pb and 208Pb was observed at scattering angles of 55 0 90 0 , and 125 o. Photons with energies between 9 and 16 MeV were used to excite the target nuclei. The incident photon beam was provided by the University of Illinois Tagged Photon Facility and had …

Giant multipole resonances in lead-208
"The differential photoneutron cross section of 208pb in the energy region 9.9 through 11.2 MeV was measured with gamma energy resolution of approximately 100 KeV using the University of 111inois bremsstrahlung monochromator. Neutrons from a 72% enriched 208pb target and an 88% enriched 206po …

Forward to backward asymmetry of the photoneutron cross sections of calcium and lead in the energy region of the isovector electric quadrupole resonance
This experiment measured the photoneutron cross sections of Ca at 55°, 90°, and 125° between E')' = 28 to 38.8 MeV for residual excitation energies less than 4 MeV. From the 55° and 125° data a forward-to-backward asymmetry A = du/dfl(55°) -du/dfl(125°) du/dfl(55°) du/dfl(125°) was extracted. These …
