Improvements in differentiation unfolding of radiation spectra
Description
Differentiation unfolding is widely used for measurements of neutron spectra in reactors using proton-recoil proportional counters and for measurements of neutron and gamma-ray spectra using scintillators. Current differentiation unfolding codes use various least-squares fits of polynomials to estimate the derivative of numerical data. Simple examples are used to illustrate the errors in unfolded energy spectra that result from the use of least-squares differentiation. An alternative method of numerical differentiation is presented; this method is shown to be free of the errors that result from least-squares differentiation
