High-spin states of (84)Sr are populated through the reaction (70)Zn ((18)O, 4n) (84)Sr at the beam energy of 75 MeV. The measurements of excitation functions, γ-γ coincidences, directional correlations of oriented states (DCO) ratios and γ-transition intensities are performed using eight anticompton HPGe detectors and one planar HPGe detector. Based on the experimental results, we establish a ...

The Spectral Deconvolution Analysis Tool (SDAT) is being written to improve counting statistics and detection limits for nuclear explosion radionuclide measurements. SDAT will utilize spectral deconvolution spectroscopy techniques to analyze both β−γ coincidence spectra for radioxenon isotopes and high-resolution High Purity Germanium (HPGe) spectra that are utilized for aerosol monitoring. Spe...

The two counting modes: a normal with a single HPGE detector and second with the additional anti-Compton shield of the annular NaI(Tl) detector have been compared for fast determination of the activity concentration of thorium 232Th in the building materials. The 232Th activity concentration was calculated by measurement of its decay products: 212Pb, 212Bi and 208Tl as well 228Ac content. Altho...

the present paper measures natural radioactivity in different areas of wassit governorate, using (hpge) detector. gamma spectrum analysis for each sample along with caululated specific activity show that the average concentrations of u-238, th-232, and k-40 have been 19.420±4.7 bq/kg, 18.487±5.05 bq/kg, and 204.266±46.9 bq/kg respectively, which is lower than the worldwide average value. while ...

This document contains a proposal of the BEPC-II collider beam energy calibration system (IHEP, Beijing). The system is based on Compton backscattering of carbon dioxide laser radiation, producing a beam of high energy photons. Their energy spectrum is then accurately measured by HPGe detector. The high-energy spectrum edge will allow to determine the average electron or positron beam energy ε ...

A measurement station dedicated for quantitative radiological characterisation of naturally occurring radionuclides in a metallurgical company and based on gamma-ray spectrometry was developed. The station is intended for performing quality control of final non-ferrous metal products and for radiological checks of incoming materials. A low-background point-contact HPGe-detector was used and the...

Nondestructive assay of gamma-ray emitting nuclear waste requires modeling because it is not practical to prepare a standard that matches the physical and nuclear properties of every waste item. The use of a high-purity germanium (HPGe) detector simplifies the spectral analysis process. Many models use simplified efficiency determinations and attenuation corrections. These models often work wel...
