A NEW POSSIBILITY OF ACQUIRING INFORMATION ON THE DISPERSE COMPOSITION OF COLLOIDAL SYSTEMS

A new method for solving the inverse problem of the spectroscopy of dy namic light scattering is suggested, and the principles involved are b riefly outlined. The development of computer programs for data process ing is discussed. These programs are merged into the KLUB software pac kage and can be used with any IBM-compatible computer for solving inve rse problems that can be reduced to a Fredholm integral equation of th e first kind. The results of a computer simulation that are presented show the accuracy in restoring the unimodal (delta-shaped) size distri butions of scattering particles. The influence of an error in register ing the auto-correlation function on the optimal value of the regulari zation parameter used for processing the correlation curve is demonstr ated.
