Abstract :
The usual least squares fitting technique for gamma spectrum analysis has been expanded to include the computation of gain and baseline shifts. An iterative nonlinear technique is used. Since the shifting parameters are determined from the sample spectrum, no additional calibration data are needed. Implementation provided fitting up to 14 standards using an 8K PDP-8 with DECtape.
