【 摘 要 】

A convenient and robust procedure for Mssbauer analysis based on Monte Carlo methodis described. The method uses simulated annealing approach to find the optimum Mssbauerparameters in the Lorentzian profile as initial values for the Monte Carlo search program.A succession of solutions to the function describing the spectrum is then randomlygenerated until the solution with the minimum chi-square with respect to the experimentaldata is reached. The result having the reduced chi-square close to 1 shows the validity ofthe method.
