Surveying.a vertical section of the ground surface taken at right angles to a survey line. Also callednuclear cross section.Physics.a quantity expressing the effective area that a given nucleus presents as a target to a bombarding particle, giving a measure of the probability that the particle ...
This gives the macroscopic cross section another useful meaning as the reciprocal of the mean-free-path. In other words, within a distance x, a radiation particle on average will encounter xmfp=Σx interactions. That is, ∑ can also be viewed as the average number of interactions per unit ...

We add the constraint that the new physics must also be consistent with published pp cross section measurements, using cosmic ray observations, an order of magnitude and more above the knee. We find that the rise in cross section required at energies above the knee is radical. The increase ...
For a comparison between the free evolution and evolution through a double slit (see section Cross-Wigner function and Gouy phase in the double-slit experiment), we show, in Fig. 6a, the normalized cross-Wigner from Eq. (15) between the initial state and the state at the time t (the ...
Based on a graphical investigation of the streamlines, this represents the absorption cross section, and forms a far-field absorption aperture. In the near-field of the oscillator, a modification of the aperture is observed. As in the case for a linear dipole, we model the energy flow and ...
A prism is a three dimensional solid that has two identical ends, flat faces and uniform cross-section along its length. Regular and irregular prism. Learn formulas of the prism at BYJU’S in an easy way.

The sum in Eq. (11) is over accessible final wavevectors as shown in Fig. 3c, and each term in the sum corresponds to a separate diffraction peak. GB strain field scattering In this section, we consider the specific problem of scattering from the strain field of grain boundaries, using ...
