Reverse Monte Carlo

Reverse Monte Carlo (RMC) is a simulation method, based on a variation of the Metropolis algorithm, which allows one to solve an inverse problem by adjusting the parameters of the model till the good consistency with experimental data is obtained.

In our laboratory, we use computationally more efficient realization of the RMC method, based on the evolutionary algorithm, to perform interpretation of EXAFS spectra by reconstructing the 3D atomic structure of a solid.

The use of the RMC method allows us to overcome problems related to accurate accounting for disorder effects beyond the first coordination shell of an absorbing atom, in the region, where a contribution of the multiple-scattering (MS) effects, related to many-atom correlation functions, is not negligible.
