A Critical Comparison of Measured and Calculated Fission Ratios for ZPR-III Assemblies

“…The spectrum change is caused by inelastic scattering in the chamber walls, and the original measurements by Davey and Curran using the Argonne Fast Source Reactor have now been supplemented by measurements in ZPR-III Assemblies 35 (7) and 38 (8) and by a number of DSN calculations by the author, all these data being given in Appendix I.…”

“…A. Measurements in ZPR-III Assemblies 35 (7) and 38 (8) These measurements investigated both the effect of chamber wall thickness and the effect of adding an extra 3-in. length of cable behind the chamber.…”
