Xenon-135 turned out to have a neutron capture cross-section of well over 2 million barns.

Chemical elements with a sufficiently high neutron capture cross-section include silver, indium and cadmium.

Gadolinium-157 has the highest thermal neutron capture cross-section among any stable nuclides: 259,000 barns.

This material has the advantage of a low neutron capture cross-section, but has two major disadvantages:

Heavier elements have larger nuclei, therefore they have a larger neutron capture cross-section and are more likely to be activated.

Zirconium is a good nuclear fuel-rod cladding metal, with the desirable properties of a very low neutron capture cross-section and good chemical stability at high temperatures.

Activation analysis: charged particle and fast neutron activation, reactor activation, neutron capture cross-sections and resonance integrals, standard, single comparator and addition methods.

Adding neutrons to isotopes can vary their nuclear spins and nuclear shapes, causing differences in neutron capture cross-sections and gamma spectroscopy and nuclear magnetic resonance properties.

In addition, Li, Be, and F are among the few nuclides with low enough thermal neutron capture cross-sections not to poison the fission reactions inside a nuclear fission reactor.

U-234 has a neutron capture cross-section of about 100 barns for thermal neutrons, and about 700 barns for its resonance integral-the average over neutrons having various intermediate energies.

If only the man had a neutron capture cross-section like cadmium's ... And then, to make his day complete, Barbara came strolling up the walk toward the apartment she and Sam Yeager were using.

Gadolinium-157 has the highest thermal neutron neutron capture cross-section of any known nuclide with the exception of xenon-135, 49,000 barn (unit), but it also has a fast burn-out rate, limiting its usefulness as a nuclear control rod material.

Hafnium's large neutron capture cross-section makes it a good material for neutron absorption in control rods in nuclear power plants, but at the same time requires that it be removed from the neutron-transparent corrosion-resistant zirconium alloys used in nuclear reactors.
