Elastic scattering, or small [omega], implies that there is negligible neutron wavelength change through the spectrometer and therefore the second cosine term in Eq.
NRSE]), the elastic scattering polarization along x, [P.
15 (top) shows the elastic scattering from an incoherent scatterer, where only three of the blades are aligned.
Our model and theory of gravity [11] is based on a flux of particles, and the "narrow beam" is interpreted due to very low-angle elastic scattering of external particles by the nucleons of the celestial bodies [11,12], particularly the Moon (near body in [12]) and Sun (far body), such that some particles never reach the detecting apparatus such as pendula, gravimeter, or radioactive source-detector system.
In the interaction of a light ion with nuclei, elastic scattering is the largest of all partial cross sections.
Our previous works dealt with studies the elastic scattering of hadrons either with stable nuclei [26, 27] or exotic nuclei [28].
In the absence of resonances it can be shown that the PV helicity dependence of the total cross section vanishes if only elastic scattering is present and that both the PV neutron spin rotation and the PV helicity dependence of the total cross section with inelastic channels are constant in the limit of zero neutron energy [23].

y] in np elastic scattering gives rise to a left-right centroid shift of the beam--this is mitigated by the very low energy of the beam with an estimated analyzing power [A.
Backscatter is an elastic scattering process, to a first order dependent on the number of protons in the nucleus and to a second order on its effective nuclear charge.
The consequences of elastic scattering are the reduction of beam current within the focused probe and redistribution of this current to form a wide "skirt" around the beam, significantly degrading the spatial resolution of x-ray microanalysis.
This scattering length determines the low energy elastic scattering rate and thus the evaporative cooling rate as well as the nonlinear coupling parameter in the Gross-Pitaevski equation (5) for the condensate wavefunction, It is not necessary to produce a condensate to measure the s-wave scattering length: temperatures in a magneto-optic trap (MOT) are sufficiently low ([approximately equal to] 1 mK) to limit scattering to a few partial waves and thus permit a determination of the s-wave scattering length.
