Tikhonov regularization procedure

Experience in using the iterative procedure for solving the inverse problem by the Tikhonov regularization method in EXAFS spectroscopy shows that the obtained solution can be improved by performing a few iterations. 

Two procedures based on Eq. 8.39 have been proposed to infer the molecular weight distribution from the relaxation modulus. Maier et al. [39] used Tikhonov regularization to invert the integral, whereas Thimm et aZ. [36 ] used an analytical relation between the relaxation function, H t) and the molecular weight distribution.
