Neutron Cross Sections

Up to date curated data provided by mathematica s elementdata function from wolfram research inc.

Neutron cross sections. Equation 1 76 is very similar to eq. 1 77 i 0 i d i. Numerical values of n g cross sections are available for a total of 739 targets for the elements h z 1 a 1 to cm z 96 a 248 totaling 972 reactions.

1 76 d i i n σ d x. Neutron cross section definition of cross section. In conjunction with the neutron flux it enables the calculation of the reaction rate for example to derive the thermal powerof a nuclear power plant.

In general the cross section is an effective area that quantifies the likelihood of. In nuclearand particle physics the concept of a neutron cross sectionis used to express the likelihood of interaction between an incident neutronand a target nucleus. Click here to buy a book photographic periodic table poster card deck or 3d print based on the images you see here.

The ngatlas contains neutron capture cross sections in the range 10 5ev 20mev as evaluated and compiled in recent activation libraries. Neutron cross section of the elements point to the graph to see details or click for full data on that element. The coefficient is a function of the number of nuclei n in the path of the neutron beam.

Select the element and you will get a list of scattering lengths and cross sections. Plots of the pointwise data and comparisons with the available experimental values at thermal energy 30 kev and 14 5 mev can be found in the report indc nds 362 iaea vienna 1997 available upon. The extent to which neutrons interact with nuclei is described in terms of quantities known.

All of this data was taken from the special feature section of neutron scattering lengths and cross sections of the elements and their isotopes in neutron news vol.
