Many of the isotopes of curium have what seem to be superficially positive properties : low critical mass requirements, high neutron absorption cross sections, long half-lives.

It is difficult to use for cooling fission-based nuclear reactors, because indium has a high absorption cross section for thermal neutrons, efficiently absorbing them and inhibiting the fission reaction.

:Zircaloy's major advantage over other cladding options is that it has a very low neutron absorption cross section . talk ) 13 : 21, 14 March 2011 ( UTC)

Pu-240 does have a moderate thermal neutron absorption cross section, so that Pu-241 production in a thermal reactor becomes a significant fraction as large as Pu-239 production.
15.
It gives the absorption cross sections of photons around the ionization edge, that is in the energy range of XANES . The calculation is performed with all conditions of rectilinear or circular polarization.
16.
In the context of ozone shielding of ultraviolet light, "'absorption cross section "'is the ability of a molecule to absorb a photon of a particular wavelength and polarization.
17.
When a gamma ray passes through matter, the probability for absorption is proportional to the thickness of the layer, the density of the material, and the absorption cross section of the material.
18.
N is the number density of molecules per cm 3, E is the photon energy ( J ), ? ( 2 ) is the two-photon absorption cross section ( cm 4 s / molecule ).
19.
The absorption cross section for thermal neutrons is 0.18 barn for zirconium, which is much lower than that for such common metals as iron ( 2.4 barn ) and nickel ( 4.5 barn ).
20.
Deuterium's absorption cross section for thermal neutrons is about 0.52 millibarns, whereas that of oxygen-16 ( ) is about 0.19 millibarns and that of oxygen-17 ( ) is about 240 millibarns.
