Abstract :
In this paper, a simple and automatic method for smoothing gamma-ray spectra is derived. This method is based on B-spline basis functions with least squares fitting used to reduce the influence of statistical fluctuations. The results show that this method is better than traditional method with a more complete reduction of statistical fluctuation.
