5 Neutron reaction cross sections •Total microscopic neutron cross section is expressed as: σ= dN/dt / [(I/A) n A ∆x] • Defining neutron flux as: φ= I/A (neutrons/sec.cm2) • Then: dN/dt = φ(A ∆x n σ) • Neutron flux can also be defined: φ= nnvn where: nn is neutron density per cm3 in beam, vn relative velocity (cm/sec.) of neutrons in beam

Although tailored TEM characterization provides both plan and cross-section views of GB structures in MHP films, the GB network in practical PSCs can be even more complex to assess.

The absorption cross-sections. Most of the measurements of the absorption cross-sections, c , , have been made by the transmission method, which measures ab s total cross-sections. The most reliable values of the scattering cross-sections for subtraction seem to be the following: UT233 U 235 239 12.5 -1.0 b OLEKSA (1958) 15 - 2.5 b FOOTE (1958)

Uranium 235 is a fissile isotope, and its fission cross-section for thermal neutrons is about 585 barns (for 0.0253 eV neutron). For fast neutrons, its fission cross-section is on the order of barns.Most absorption reactions result in fission reaction, but a minority results in radiative capture forming 236 U. The cross-section for radiative capture for thermal neutrons is about 99 barns (for

If I remember correctly, it's something to do with the chance that a U235 atom will absorb a neutron (as opposed to it causing fission). Press J to jump to the feed. Press question mark to learn the rest of the keyboard shortcuts. Search within r/ExplainLikeImPHD. r/ExplainLikeImPHD.
