The neutron cross sections provide information about what happens to the neutrons when they pass with atoms of the material. For this reason, 

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 relative to the cross section standards. The most recent evaluations were completed in 2005 and a report was published in 2007 (STI/PUB/1291).

11/19 · Alternative methods to calculate neutron capture cross sections on radioactive nuclei are reported using the theory of inclusive non-elastic breakup (INEB) developed by Hussein and McVoy (Nucl. Phys. A. 445, p. 124, 1985). The statistical coupled-channels theory proposed in Bertulani et al. (Eur. Phys. J. Web Conf. 69, 00020, ) is further extended in the realm of

The thermal neutron scattering cross-section of a solid depends on the energy (or wavelength) of the incident neutrons.

In general, the neutron cross-section is an effective area that quantifies the likelihood of certain interaction between an incident neutron 

A P/sub 3/, 218 neutron group cross-section library in the AMPX master interface format has been generated from ENDF/B-IV data for 65 nuclides of primary interest in criticality safety calculations. The library was generated with the AMPX modular code system. Procedures used to generate the cross sections and the organization of the library are

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

1/v Region. In the common case, the cross section is usually much larger at low energies than at high energies. For thermal neutrons (in 1/v region), also radiative capture cross-sections increase as the velocity (kinetic energy) of the neutron decreases. Therefore the 1/v Law can be used to determine shift in capture cross-section, if the neutron is in equilibrium with a surrounding medium.

the energy spectrum of the neutron beam and the quality of the neutron beam used in nct are critical, as these factors have a direct relation to the overall therapeutic effect. 260 the high neutron capture cross section of 157 gd and 155 gd toward thermal neutrons has been clearly established, and it is highest for neutron energies equal to 0.032
