Investigation of prompt γ-ray neutron activation spectrometer at the Dalat research reactor using Geant4 simulation
2023, Radiation Physics and ChemistryPerformance of various mathematical functions for the in-situ relative detector efficiency towards its applicability for k<inf>0</inf> IM-NAA
2022, Applied Radiation and IsotopesCitation Excerpt :Various mathematical functions were reported by several authors (Table 1) for the calculation of the relative efficiency curve for different ranges of gamma energies for the detectors used in the gamma spectrometry (Kis et al., 1998). The precisely known intensity ratios and the point-pair method were used to obtain the efficiency curve by Kane et al. (Kane and Mariscotti, 1967). Aksoy divided the function for two different ranges of energies and used 5th order polynomial at low-energy (<300 keV) but however used 4th order polynomial for higher energy to achieve the weighted mean deviation of 1% between the measured data and fitted curve (Aksoy, 1993).
Calibration of semiconductor detectors in the 200-8500keV range at VNIIM
2012, Applied Radiation and IsotopesCitation Excerpt :The main problem for this project is the lack of standard sources emitting photons at energies above 2614 keV (Bé et al., 1998–2011). Other workers have used the (n,2γ) and (n,γ) reactions on targets containing chromium, titanium, chlorine and nitrogen to produce gamma-rays in this energy region (Kane and Mariscotti, 1967; Belgya, 2008; Acharya et al., 2001; Molnar et al., 2002). The authors of the work presented here chose mercury, chlorine and titanium due to the high thermal neutron cross-sections of these elements.
