The resonance neutron capture cross section of /sup 89/Y has been measured between 2.5 and 100 keV with the neutron capture facility at the 40-m flight station on the Oak Ridge Electron Linear Accelerator. Resonance parameters were extracted for levels below 50-keV bombarding energy.

Xenon-135 is a product of U-235 fission and has a very large neutron capture cross-section (about 2.6 x 106 barns). Boronis commonly used as a neutron absorber due to the high neutron cross-section of isotope 10B. Its (n,alpha) reaction cross-section for thermal neutrons is about 3840 barns (for 0.025 eV neutron).

In the astrophysically relevant energy range, 9Be belongs to the handful of isotopes among the entire periodic table. (together with carbon, nitrogen, oxygen, 

The cross section is not in general equal to the actual area of the nucleus. For instance the radiative capture cross section for Au197 at the peak of 4.9 eV resonance is 3x10-20 2cm , whereas the geometrical area of its nucleus is just 1.938x10-24 cm2. The reaction cross section is much greater than the physical cross section of the nucleus

Currently, the ratio of the dose for fast neutrons over epithermal neutron fluence is accepted to be from 2.5·10 -13 to 13·10 -13 Gy·cm 2 /n and from 1·10 -13 to 13·10 -13 Gy·cm 2 /n in case

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

Neutron capture and total cross sections of 155Gd and 157Gd were measured with the neutron time-of-flight method in Accurate Neutron-Nucleus Reaction measurement Instrument at Material and Life Science Experimental Facility of the Japan Proton Accelerator Research Complex using the NaI (Tl) spectrometer and Li-glass detectors.

Gadolinium-157 has the highest thermal-neutron capture cross-section among any stable nuclide.Based on my layman's understanding of neutron capture - particularly the fact that (I assume) neutrons don't much care about electron shells - I would have guessed that neutron capture cross-section would be proportional to either:. Size of the nucleus.

The neutron absorption on 135 Xe has a cross section reaching atomic values, but for other neighboring isotopes the cross sections are inexplicably much smaller. A list of empirical neutron capture cross sections on several nuclei is shown in Table 1, with data extracted from Refs. [ 40, 41, 42 ].
