A COMPUTER PROGRAM FOR UNFOLDING PULSE-HEIGHT DISTRIBUTIONS,

Abstract : The pulse-height distribution obtained from a scintillation spectrometer is an instrumental distortion of the gamma-ray spectrum for which it is a measure. By calibrating the detector with radioactive sources of known strength and gamma energy, a representation of this distortion may be embodied in a detector response matrix. A series of computer programs are presented which aid in forming this matrix and in using it to effect a mathematical transformation from the measured pulse-height distribution to the desired gamma-ray spectrum.
