A Least-Squares Polynomial Fitting to Simulate Cross Section Variations in Cd-106

Abstract

The data were statistically analyze to the International Atomic Energy Agency(IAEA) like EXFOR and ENDF Libraries, to be assess the statistical data of the experimental cross section for isotope cadmium Cd-106 of a thick target element, to appoint cross sections of nuclear reactions.That have energy range starting from threshold energy for induced neutrons in the isotope cadmium Cd-106.The relation shape between cross section and energy has been represented depending on least squares polynomial orthogonal taking into consideration the amount of cross section uncertainties.Weight average was calculated relay on uncertainties by using three method (the weight mean error,the absolute error,and the sum error) an estimate of the adopted values the weighted average cross sections and their respective uncertainties are also given.
