neutron absorption cross-section

This material was selected because of its low neutron absorption cross-section.

Xenon-135 was indeed the culprit; it turned out to have an unexpectedly large neutron absorption cross-section.

Technically, studying 3He with neutrons is made very difficult by the huge neutron absorption cross-section.

Wartime experiments included measuring the neutron absorption cross-section of elements and compounds.

The temporarily high level of Xe with its high neutron absorption cross-section makes it difficult to restart the reactor for several hours.

Both have high neutron absorption cross-sections, so that much of them produced in a reactor are later destroyed there by neutron absorption.

It has a half-life of about 9.2 hours and is the most powerful known neutron-absorbing nuclear poison (having a neutron absorption cross-section of 2 million barns).

Commercial non-nuclear grade zirconium typically contains 1-5% of hafnium, whose neutron absorption cross-section is 600x that of zirconium.

Continuous processing would reduce the inventory of fission products, control corrosion and improve neutron economy by removing fission products with high neutron absorption cross-section, especially xenon.

A neutron poison (also called a neutron absorber or a nuclear poison) is a substance with a large neutron absorption cross-section, in applications such as nuclear reactors.

Because of a low neutron absorption cross-section and weak damage sensitivity under irradiation, it finds use as the coating of uranium dioxide and thorium dioxide particles of nuclear fuel.

The separation of hafnium is especially important for nuclear applications since hafnium has very high neutron absorption cross-section, 600 times higher than zirconium, and therefore has to be removed for reactor applications.

Xe has a very large neutron absorption cross-section, so in the high neutron flux environment of a nuclear reactor core, the Xe soon absorbs a neutron and becomes stable Xe.

Dysprosium is used for its high thermal neutron absorption cross-section in making control rods in nuclear reactors, for its high magnetic susceptibility in data storage applications, and as a component of Terfenol-D.

Spent LWR fuel is mostly depleted uranium and, in a TWR fast-neutron spectrum, the neutron absorption cross-section of fission products is several orders of magnitude smaller than in a LWR thermal-neutron spectrum.

Since I has a modest neutron absorption cross-section of 30 barns, and is relatively undiluted by other isotopes of the same element, it is being studied for disposal by nuclear transmutation by re-irradiation with neutrons or by high-powered lasers.

Thermal neutrons have a different and often much larger effective neutron absorption cross-section for a given nuclide than fast neutrons, and can therefore often be absorbed more easily by an atomic nucleus, creating a heavier, often unstable isotope of the chemical element as a result (neutron activation).
