# Energy-dependent neutron cross section data

Where I can find a table with energy dependent cross sections for neutrons?

• neutron scattering against what? protons? you can start with the particle data book pdg.lbl.gov – anna v Apr 3 '14 at 11:11
• This kind of data is most often accumulated in ENDFs, which are intended for computer consumptions, but can be read by a sufficiently persistent human. Many sources. – dmckee --- ex-moderator kitten Apr 4 '14 at 0:05

A good approximate parametrization of the neutron-hydrogen elastic cross-section in units of barns is given by $$\sigma(E)=\frac{3 \pi }{(0.13 E+0.4223)^2+1.206 E},$$ as shown here:
