The angular correlation factor in gamma-ray coincidence summing
The intensity of coincidence summing in γ -ray spectroscopy depends on the angular correlation function, which determines the probability for the γ rays to be emitted in the same direction. This factor is generally negligible in accounting for the reduction in peak intensities due to summing, but it...

| Zusammenfassung: | The intensity of coincidence summing in γ -ray spectroscopy depends on the angular correlation function, which determines the probability for the γ rays to be emitted in the same direction. This factor is generally negligible in accounting for the reduction in peak intensities due to summing, but it can have significant effects in accounting for the intensity of coincidence sum peaks. In the experiments described in the present report, we have determined the angular correlation factor for a variety of coincidence sum peaks in both simple and complex decays, and we show how the coincidence sum peak can provide a unique signature of 0+ states in nuclei. |
