The neutron cross section σ can be defined as the area in cm2 for which the number of nuclei–neutron reactions taking place is equal to the product of the

The neutron cross-section is variable and depends on: Target nucleus(hydrogen, boron, uranium, etc.). Each isotop has its own set of cross-sections. Type of the reaction(capture, fission, etc.). Cross-sections are different for each nuclear reaction. Neutron energy(thermal neutron, resonance neutron, fast neutron).

The ratio of the thermal-neutron capture cross-sections of boron and hydrogen was found to be 2317 ± 27. The cross-section of hydrogen calculated from this 

During the Manhattan Project, physicists needed to predict the probability of a free neutron striking the nucleus of a fissionable substance, forcing the nucleus to undergo fission. The area within which fission would be expected to occur, is defined to be the "fission cross-section." Fission is not the only potential interaction between

The mechanism is based on the high neutron-capture cross section of the stable isotope 6 Li for thermal neutrons according to the 6 Li (n,α) 3 H reaction illustrated by Eq. 11.36 earlier in this chapter. Capture of thermal neutrons by 6 Li produces an alpha particle and triton with 4.8 MeV energy liberated as kinetic energy of the reaction

Specifically, a suitable epithermal neutron flux (ϕEpi) of about 1×109 (n.cm−2.s−1) for BNCT and high quality thermal neutron flux (ϕTh) of above 1×106 (n.cm−2.s−1)for NR are carried

Neutron Capture Cross-section The radiative capture cross-section represents the likelihood of a neutron radiative capture as σγ . As usual, the cross-section can be divided into three regions according to the incident neutron energy. 1/v Region Resonance Region Fast Neutrons Region 1/v Region
