Incoherent elastic neutron scattering from vanadium has been employed to determine the mean-squared displacement ''< u/sup 2/ >/sub T/'' through the Debye-Waller exponent for the temperature range between 4.2 and 296 K. Significant corrections to the scattering data arise from (i) primary scattering due to the cylindrical shape of the …

WebThe Compton effect is the elastic scattering of photons from electrons. As a reaction, the process is: γ +e −→ γ +e . Since this is a two body elastic scattering process, the angle of the scat-tered photon is completely correlated with the energy of the scattered photon by energy and momentum conservation. This relation is usually ... WebAug 1, 2005 · Elastic scans.
