Anomalous Asymptotic of Small-Angle Neutron Scattering Intensity

Section: Soft matter
Language: Ukrainian

Abstract: An anomalous asymptotic dependence of the small-angle neutron scattering intensity I(Q), when I(Q) increases infinitely as Q → 0, has been studied. This behavior is shown to be associated with the presence of the random field of a scattering density, whose typical linear size is much larger than the reciprocal magnitude of Q. In the considered case, the sought asymptotic dependence is found to have the form I(Q)~Q−3.

Key words: small-angle neutron scattering, classical asymptotics, anomalous asymptotics.
