This makes the resulting thermal (‘slow’) neutrons fall right within the neutron cross section for U-235 and a few other elements (e.g. Pu isotopes), but incapable of fissioning most ...

Typically, in nature, when the cross section for neutrons with a kinetic energy of 25 meV (thermal cross section) is very large, the resonance integral is small." ...

The NGATLAS contains neutron capture cross sections in the range 10-5eV - 20MeV as evaluated and compiled in recent activation libraries. Numerical values of (n,g) cross sections are available for a ...

So far, the capture cross-section of thermal neutrons in thorium has not been measured. The following experiments were carried out in order to determine this cross-section.

Thermal Scattering: The process by which neutrons interact with a material at thermal energies, usually close to room temperature. Neutron Cross Section Measurements and Nuclear Data Analysis ...

Most of the accessible data are taken from the Evaluated Nuclear Structure Data File (ENSDF), which is the most authoritative and up-to-date database in this area. In addition, other data of interest, ...

To mitigate neutron moderation by hydrogen, replace light water (H₂O) with heavy water (D₂O, deuterium oxide). Deuterium has a much lower neutron capture cross-section (0.0005 barns vs. 0.33 barns for ...
