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." ...

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 ...

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.

Neutron cross section measurements and nuclear data analysis are fundamental to advancing our understanding of nuclear interactions and improving the design of nuclear systems.

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, ...

The UK's National Physical Laboratory has announced plans for a new neutron measurement facility at its site in Teddington, south-west London. The new accelerator system will be six times as powerful ...
