I am looking for thermal neutron scattering cross sections (0.025eV) for individual isotopes, having found non isotopic data for most elements in a textbook. The most comprehensive cross section database appears to be http://www.nndc.bnl.gov/sigma/index.jsp?as=238&lib=endfb7.0&nsub=10". Unfortunately I am unable to identify which plots if any could give me the scattering cross section. Presumably all (n,elastic) collisions must be scattering but n(inelastic) could either be a scattering or absorption event. When the scattering cross section is usually quoted (as typically in textbooks) does that usually include elastic and inelastic collisions? Am I also correct in thinking that neutron scattering data will generally be poor for isotopes with very high absorption cross sections such as boron-10?
