of a nucleus capturing a neutron at a given kinetic energy is called neutron-capture cross section," Thanos Stamatopoulos, first author of the paper, told Phys.org. "The probability across several ...

Neutron cross section standards are important in the measurement and evaluation of all other neutron reaction cross sections. Not many cross sections can be defined as absolute - most are measured ...

and two, what is the likelihood of neutrons colliding with nuclei, also known as neutron cross section?” Amberger explained. “My work with Phil is trying to improve our understanding of the ...

The NGATLAS contains neutron capture cross sections in the range 10-5eV - 20MeV as evaluated ... available upon request from the IAEA Nuclear Data Section.

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 ...

This is quite unlike 235 U, which has a solid fission cross section, but only at neutron speeds which are significantly lower than those of freshly emitted neutrons during the nuclear chain reaction.
