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 ...

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 ...

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 ...

EXPERIMENTS on the processes arising in thorium under neutron bombardment have shown ... So far, the capture cross-section of thermal neutrons in thorium has not been measured.

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