It can be observed that with the increasing of the incident angle, the specular coherent scattering decreases, while the width of the specular peak becomes wider.
The spectra shown in Figures 7(c) and 7(d) were calculated for the case of coherent scattering from a cubic sample of 800 nm in size consisting of N = 400 clusters.
Then we discussed the coherent scattering mechanism and established the mathematical modeling of the receiving power and electron density of irregularities.
The situation is drastically different at coherent scattering of neutrinos on nuclei.
Based on the analysis mentioned above, including the influences of the BSC on the rms height and the correlation length, more coherent scattering contribution to the BSC under this condition ([delta] = 0.1 [lambda], l = 0.5[lambda]).
Results from measurements at NIOF of the n-p [b.sub.np] = (-3.738 [+ or -] 0.002) fm and n-d [b.sub.nd] = (6.665 [+ or -] 0.004) fm coherent scattering lengths [14] showed that essentially all existing calculations of the n-d coherent scattering length are in serious disagreement with experiment and that the accuracy of present measurements is sensitive to nuclear three-body forces.
Key words: coherent scattering length; neutron interferometry; nondispersive phase.
Here we use PO for calculation of coherent scattering from faces and PTD for the calculation of diffraction from edges.
The spin independent part of the quantity is referred to as the coherent scattering length [a.sub.c].
In the above equation, j denotes the atomic species, m is the neutron mass, [b.sub.j] is the coherent scattering length, [delta] is the delta function, r is the coordinate of the neutron, and [R.sub.j] is the coordinate of the atomic scattering center.
