“…The contribution of terms (coincident energies) having coefficients of less than five per thousand is not considered since their contribution in the correction factor is generally on the order of fractions of a percent. The correction equations are found to be comparable with those calculated in other studies [26][27][28], within few percent on the coefficients terms. The ''apparent'' full energy peak efficiency (e p ) and total efficiency (e t ) (Fig.…”

“…The uncertainties of components are assessed either by Type A or by Type B evaluations. Type A evaluation is based on a statistical evaluation of measurement data, as in the case of the counting uncertainty which is normally evaluated Terms for c-KX-ray coincidence summing are taken from bibliography [26][27][28] J Radioanal Nucl Chem according to the Poisson statistics. Type B evaluation is performed by any other method, e.g.…”

The feasibility of using certified reference\ud materials for the full energy efficiency calibration of p-type\ud coaxial high-purity germanium detectors for the determination\ud of radioactivity in environmental samples is discussed.\ud The main sources of uncertainty are studied and the\ud contributions to the total uncertainty budget for the most\ud intense gamma lines are presented. The correction factors\ud due to self-absorption and true coincidence summing\ud effects are discussed in detail. The calibration procedure is\ud validated for natural and artificial radionuclide determination\ud in different matrices through an internal cross-validation\ud and through the participation in a world-wide open\ud proficiency test

“…A comparison has been made for coincidence correction factors between this work and other studies (Table 2). Schima and Hoppes (1983) used an analytical expression which is a good agreement with the measured data in the present work ( Table 2). The values listed from the work of Dias et al (2002) are measured on Monte Carlo calculations, and those reported by Arnold and Sima (2004) are measured using HPGe detector with a 50% relative efficiency.…”

Peak-to-total (P/T) calibration Gamma ray spectrometry Gennie 2000 a b s t r a c tThe coincidence summing corrections for an HPGe spectrometer with Marinelli-beaker geometry were calculated using the peak-to-total (P/T) calibration method in combination with the algorithms implemented in the Genie 2000 software. The P/T ratios were calculated for different energies and three types of beaker contents: air, powder milk and soil. The validity of the correction was tested against a standard sample and showed excellent agreement with the certified data. The corrections were also in good agreement with published data in the literature.

“…However, because of the high counting efficiency of the detector system, summing correction has to be applied for the multiple line sources. These were taken from Ref [33]. The second method makes use of the high counting efficiency and granularity of the detection system.…”

The 106 Cd(α, γ) 110 Sn reaction cross section has been measured in the energy range of the Gamow window for the astrophysical p-process scenario. The cross sections for 106 Cd(α,n) 109 Sn and for 106 Cd(α,p) 109 In below the (α,n) threshold have also been determined. The results are compared with predictions of the statistical model code NON SMOKER using different input parameters. The comparison shows that a discrepancy for 106 Cd(α, γ) 110 Sn when using the standard optical potentials can be removed with a different α+ 106 Cd potential. Some astrophysical implications are discussed.
