Neutron Total Cross Sections and Resonance Parameters of Palladium

The coherent neutron scattering lengths and total cross sections of elemental and oxide samples of natural and isotopically enriched W are determined. From these results the following coherent scattering lengths, b, and absorptions at 0.0253 eV, σγ were deduced:b (natW) = 4.86±0.02 fm, σγ = 17.3 ±0.5 b ,b (182W) = 7.04±0.04 fm, σγ = 19.6±0.3 b ,b (183W) = 6.59±0.04 fm, σγ = 10.5±0.2 b ,b (184W) = 7.55±0.06 fm, σγ = 1.7±0.1 b ,b (186W) = -0 .7 3±0.04 fm, σγ = 38.5 ±0.8 b .By comparison with the resonance parameters, the incoherence and the potential radii are derived and discussed. The bound level on W-182 must be fitted with a scattering width of gI0n = 161 meV at E0 = - 94 eV.

Elastic And Inelastic Scattering

The theory of multiple scattering has been worked out by Groves and comparisons have been made between predicted and observed signals for thick specimens observed in a STEM under conditions where phase contrast effects are unimportant. Independent measurements of the collection efficiencies of the two STEM detectors, calculations of the ratio σe/σi = R, where σe, σi are the total cross sections for elastic and inelastic scattering respectively, and a model of the unknown mass distribution are needed for these comparisons. In this paper an extension of this work will be described which allows the determination of the required efficiencies, R, and the unknown mass distribution from the data without additional measurements or models. Essential to the analysis is the fact that in a STEM two or more signal measurements can be made simultaneously at each image point.
