abstract = {This article deals with multiple scattering effects that
are important for the method of small-angle neutron
scattering (SANS). It considers three channels for the
coherent elastic, the incoherent elastic and the incoherent
inelastic scattering processes. The first channel contains
the desired information on the experiment. Its multiple
scattering effects can be desmeared, as shown in the later
sections of the article. The other two channels display a
nearly constant background as a function of the scattering
angle. The incoherent elastic scattering is treated by the
theory of Chandrasekhar, allowing for multiple scattering
even at large scattering angles. The transfer to a single
representative thermalized wavelength by the inelastic
scattering – as a simplification – is assumed to happen
by a single scattering event. Once the transition to this
altered wavelength has happened, further incoherent multiple
scattering is considered. The first part of the paper deals
with the multiple scattering effects of light water. In the
later part of the article, deconvolution algorithms for
multiple scattering and instrumental resolution of the
elastic coherent signal as implemented in the program
MuScatt are described. All of these considerations are
interesting for both reactor-based instruments with velocity
selectors and time-of-flight SANS instruments and may
improve the reliability of the data treatment.},
