Introducing HYPERMET-PC for automatic analysis of complex gamma-ray spectra

Abstract. Measurements to determine the energy dependent branching ratio for the neutron induced capture reaction on 209 Bi were performed at the time-of-flight facility GELINA of the IRMM in Geel (Belgium). By using germanium γ-ray detectors in combination with the time-of-flight technique, the γ-ray spectra following neutron capture on 209 Bi were determined around 6 neutron resonances between 0.8 keV and 7.0 keV. The relative partial cross sections were obtained by correcting the full energy net peak areas for the effective γ-ray detection efficiency and internal conversion. The effective γ-ray efficiency was obtained from a Monte Carlo model validated through measurements with calibrated sources. The results of a preliminary analysis are given in this paper.

Radiative thermal neutron-capture cross sections for the 180 W(n, γ) reaction and determination of the neutron-separation energy Prompt thermal neutron-capture partial γ-ray production cross sections were measured for the first time for the 180 W(n, γ) reaction using a cold guided-neutron beam at the Budapest Research Reactor. Absolute 181 W γ-ray cross sections were internally standardized using well-known comparator γ-ray cross sections belonging to the other tungsten isotopes present in the 11.35%-enriched 180 W sample. Transitions were assigned to levels in 181 W based largely upon information available in the literature. The total radiative thermal neutron-capture cross section σ0 was determined from the sum of direct prompt γ-ray cross sections populating the ground state and a modeled contribution accounting for ground-state feeding from the quasi continuum. In this work, we find σ0 = 21.67 (77)

Precise Determination of Cr and Co in Certified Reference Material of Silicon Nitride by Neutron Activation Analysis Using Internal Standardization

et al. 2009

Neutron activation analysis with an internal standard correction was applied to the determination of Cr and Co in a ceramics certified reference material (NMIJ CRM 8004-a silicon nitride powder). Cesium was used as an internal standard to compensate for any inhomogeneity of the neutron flux through an irradiation capsule and to improve the repeatability of gamma-ray measurements. It was found that the linearity of the calibration curves of Cr and Co was improved by using an internal standard. The analytical results of Cr and Co in NMIJ CRM 8004-a were in good agreement with those obtained by ICP-OES, ICP-sector field mass spectrometry (ICP-SFMS), and isotope dilution/ICP-SFMS for Cr. The relative expanded uncertainties (k = 2) were 1.9% for Cr and 1.5% for Co. The uncertainties were comparable to those of atomic spectrometric methods.
