ON THE INSENSITIVITY OF THE ASYMPTOTIC-BEHAVIOR OF SMALL-ANGLE NEUTRON AND X-RAY-SCATTERING DATA TO MULTIPLE-SCATTERING

It is shown that in the limit of small-angle scattering from a plate a ny asymptotic power-law decay of the scattering intensity towards the high wavenumber, q, end of the diffraction pattern is not changed by m ultiple scattering as long as the intensity drops faster than 1/q(2). In that case, asymptotically neither the exponent nu > 2 of the 1/q(nu ) tail of the scattering intensity nor the intensity of this tail are affected by even heavy multiple scattering.
