A new method in gamma-ray spectroscopy: A two crystal scintillation spectrometer with improved resolution
A new method has been developed to measure the spectra of gamma radiation emitted in cascade disintegrations. Use is made of a two-crystal scintillation spectrometer and a gated multi-channel analysing device. The pulses produced by summing the outputs of the two crystal-photomultiplier combinations are selected by a single-channel differential discriminator. The output of this differential discriminator gates the multi-channel analyser whenever the sum pulse corresponds to the release in the crystals of the full energy available in the cascade. The spectrum displayed is that of either of the two detectors. The most important features of the technique are:
1.
(a) only “full-energy” peaks are detected;
2.
(b) improved resolution is obtained especially at higher gamma-ray energies;
3.
(c) one γ-γ or p-γ-γ angular correlation experiment determines the angular correlation of the gamma rays of all double cascades deexciting a given level.
Details of operation and typical spectra are presented. It is suggested that the technique be called the “sum-coincidence” method.
