The microscopic cross-section “σ” is used to characterize the probability of reaction between a neutron and an individual particle or nucleus.

is also common to define the macroscopic cross section Σx to group all the of nuclear reaction is characterized by a specific microscopic cross section.

233U. 233 U belongs to the group of fissile isotopes. It is produced by radiative neutron capture in nuclear reactors containing thorium fuel. 2. 236U. 236 U is neither a fissile isotope nor a fertile isotope. 236 U is fissionable only by fast neutrons. Isotope 236 U is formed in a nuclear reactor from fissile isotope 235 U.

He explains: “A microscopic cross section looks like brickwork, with flat, hexagonal tablets of a crystalline, calcium carbonate mineral stacked in neat layers. jw The distinction between macroscopic and microscopic cross - section is that the former is a property of a specific lump of material (with its density), while the latter is an intrinsic property of a type of nuclei.

The standard unit for measuring the cross section is the barn, which is equal to 10−28 m2 or 10−24 cm2. The

4/24 · This is essentially barns per nucleon (proton). Now look at pp, which goes up to ~ 10 9 GeV (~10 18 eV). At these energies, neutron and proton cross sections are about the same (minimum ~ 40 mb per nucleon at 100 GeV). For silicon, I would multiply per nucleon cross sections by ~28 2/3 = 9.3 (geometric cross section). Bob S.

The microscopic cross sectionrepresents the effective target area of a single nucleus, while the macroscopic cross sectionrepresents the effective target area of all ofthe nucleicontained in certain volume. Microscopic cross-sectionsconstitute a key parameters of nuclear fuel.

Famous quotes containing the words section, cross and/or microscopic: “ Ah, Governor [Murphy, of New Jersey], don’t try to deceive me as to the sentiment of the dear people. I have been hearing from the West and the East, and the South seems to be the only section which approves of me at all, and that comes from merely a generous impulse, for even that section

Microscopic Versus Macroscopic Cross Section. Up to now, the cross section referred to in this article corresponds to the microscopic cross section σ.However, it is possible to define the macroscopic cross section Σ which corresponds to the total "equivalent area" of all target particles per unit volume:. where N is the atomic density of target.
