摘要：

Small-angle scattering data from strong scattering systems, like pores in structural ceramics and cements, cannot be analysed invoking single scattering approximation (S. Mazumder and A. Sequeira, Pramana J. Phys. 38 (1992) 95) as specimen needed to replicate the bulk matrix in essential properties are too thick to validate the approximation. This paper deals with an algorithm to extract single scattering profile from small-angle scattering data affected by multiple scattering. The algorithm can process the scattering data and deduce single scattering profile in absolute scale. A software package, SIMSAS, has been developed for executing this inversion step. This package can be used both to simulate and to analyse multiple small-angle scattering data. (C) 1998 Elsevier Science B.V. All rights reserved.
