Since the 10B (n,α) 7Li reaction strictly depends on the incoming neutron energy and has a high cross-section at the thermal neutron energies, effects of the background cosmic thermal neutrons on the NISC are investigated in this study.
Hafnium, on the other hand, has an exceptionally high cross section, and accordingly even slight hafnium contamination nullifies the intrinsic advantage of the zirconium.
233Pa has a relatively long half-life of 27 days and high cross section for neutron capture (the so-called "neutron poison").
Like other lanthanides, many isotopes, especially isotopes with odd mass numbers and neutron-poor isotopes like 152Eu, have high cross sections for neutron capture, often high enough to be neutron poisons.
With its higher cross section, the deuterium-tritium nuclear fusion reaction became the basis of a hydrogen bomb.
Out of this series, mTFP1 has the highest cross section, σ2 ~75 GM, and G3 the lowest, σ2 ~40 GM. mTFP0.7 absorbs at the shortest wavelength, 865 nm, and G3 at the longest wavelength at 935 nm.
These strong fibre/cement interface interactions were attributed to a combined effect of different factors: fibres' surface rugosity, unusually high cross-section area, lower aspect ratio (50 times lower than a similar PAN length fibre), higher FIER and their self-fibrillation ability during mortar mixing.
The high cross-section of electrons makes it a very flexible tool for the study of light elements, monolayers and surfaces; at the same time, electrons can travel down to few nanometers (nm) and structural information from the bulk can also be retrieved.
Boron shielding is used as a control for nuclear reactors, taking advantage of its high cross-section for neutron capture.
