Nuclear scattering data
Microscopic bound-atom values. Absorption is tabulated at 1.798 angstrom; bulk absorption uses the selected wavelength.

This is an idealized independent-atom, bulk, all-angle estimate. It does not predict AGNES detector counts or QENS line shapes, and it excludes structure factor, dynamics, sample-can background, multiple scattering, detector solid angle, flux, and efficiency.
