Barnes Although the total cross section for the capture of neutrons by the element erbium is fairly well known,1 the cross section of the Er68 isotope is unkrown, while that of Er ' is somewhat uncertain.2 The capture cross sections of Era8 and ErITO may be obtained by ir- Nuclides that tend to absorb a neutron and either decay or keep the neutron in its nucleus are neutron absorbers and will have a capture cross section for that reaction. Isotopes that fission are fissionable fuels and have a corresponding fission cross section. The remaining isotopes will simply scatter the neutron, and have a scatter cross section.

Resonance Parameter Analysis of Zirconium up to 2.5 keV. G. Leinweber,* J. Burke, C. R. Lubitz, From the activity (decay rate) of the resulting radioisotopes, it is possible to deduce the cross section (probability) for neutron capture. These results have both Thermal Neutron Capture Cross Sections of Tellurium Isotopes. I. Tomandl, J. Honzéatko. Nuclear Physics Institute, 250 68 Re z, Czech Republic. T. von Egidy Total microscopic neutron cross section is expressed as: Some observations of neutron cross sections Below 1eV: probability of neutron capture or fission.
Pattenden8 and Watanabe et al.9 measured total neutron cross sections as functions of neutron energy, and deduced capture cross sections at thermal energy by subtract-ing scattering cross sections.
Measurement and analysis of the 241Am neutron capture cross
As usual, the cross-section can be divided into three regions according to the incident neutron energy. 1/v Region; Resonance Region; Fast Neutrons Region The Atlas of Neutron Capture Cross Sections (NGATLAS) contains cross sections data of neutron induced reactions for targets up to, and including, curium (Z=96). It comprises 739 target isotopes with half-lives above 0.5 day.

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. 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 Neutron Capture Cross-section.

As usual, the cross-section can be divided into three regions according to the incident neutron energy. 1/v Region; Resonance Region; Fast Neutrons Region The Atlas of Neutron Capture Cross Sections (NGATLAS) contains cross sections data of neutron induced reactions for targets up to, and including, curium (Z=96). It comprises 739 target isotopes with half-lives above 0.5 day. Cross sections to ground, first and second isomers are listed separately.
Cross sections to ground, first and second isomers are listed separately. The neutron capture cross section of an atomic nucleus is not an actual cross-sectional area, but rather a measure of the probability of that nucleus absorbing a neutron and becoming radioactive. Therefore, it can be referred to as an “effective” cross section
For fast neutrons its fission cross-section is on the order of barns. Xenon-135 is a product of U-235 fission and has a very large neutron capture cross-section (about 2.6 x 106 barns). Boron is commonly used as a neutron absorber due to the high neutron cross-section of isotope 10B. 2013-01-07
Please note that the fission cross-sections σfof all fission fuels and capture cross-sections σγof all other elements are inversely proportional to the neutron velocity at neutron energies below 1 eV range, i.e., σfand σγ~1/vor ~1E, which can be seen easily in Figs.48–50in logarithmical scale. To design innovative reactors and nuclear fuels in future, neutron capture cross-sections for MAs and LLFPs are required in the energy range from several eV to several hundreds keV.
