Abstract：
The experimental data processing method of measuring the mean-free-path of nuclear interactions is discussed. Estimator formulas in several experimental conditions are obtained by using the maximum likelihood method. The result of Mente-Carlo simulation shows that in case of the experimental data with poor statistics the maximum likelihood extimate value is more accurate than the least squares fitting value geuerally used.
