Phys. Rev. E (23feb00), resubmitted (25apr00), cond-mat/0002363) Elastic and inelastic incoherent neutron scattering experiments are simulated for simple models: a rigid solid (as used for normalisation), a glass (with a smooth distribution of harmonic vibrations), and a viscous liquid (described by schematic mode-coupling equations). As long as the spectral distribution of the input scattering law does not vary with wavenumber, it is only weakly distorted by multiple scattering. The wavenumber dependence of the scattering intensity suffers much more.

“…Following the pioneering works of Vineyard 16 , and Blech and Averbach 17 , Sears thoroughly established its theoretical basis 18 , stating the integrals that describe the contribution of the n-th scattering process to the observed spectrum. The complexity of its solution was successfully tackled by Copley 19 who devised a Monte Carlo code, suited to a particular experimental situation. However, Copley's scheme could not be easily adapted to different kinds of experiments.…”

Multiple scattering and attenuation corrections in Deep Inelastic Neutron Scattering experiments

2006

View full text Add to dashboard Cite

Multiple scattering and attenuation corrections in Deep Inelastic Neutron Scattering experiments are analyzed. The theoretical basis is stated, and a Monte Carlo procedure to perform the calculation is presented.The results are compared with experimental data. The importance of the accuracy in the description of the experimental parameters is tested, and the implications of the present results on the data analysis procedures is examined.
