Unscrambling Pulse-Height Spectra On-Line

In spite of the apparent complexity of the equations, it is shown that unscrambling scintillation spectra by a least-square-fit procedure is well suited to on-line calculations, requiring certainly no more than the very simplest of electronic computers. Unfortunately the sensitivity of the method to energy calibration errors limits its application to cases where the energies of the strong components in the spectrum are known beforehand.
