Аннотация:The problem of finding nuclear reaction yields in activation experiments is analyzed. It was shown that in the presence of complex decay chains the activity of gamma-spectrum lines of the nuclei can be described with a linear statistical model. Since the covariance matrix is unavailable the iteratively reweighted general least squares method is an appropriate means of obtaining a maximum-likelihood estimation. The relationship between the variances of estimated yields and the duration of spectrum measurements is discussed.
