A new gamma-ray spectrum catalog and library for PGAA

Abstract

New measurements have been performed at the PGAA facility at the Budapest Research Reactor (BRR) in order to create a prompt γ-ray catalog for qualitative and quantitative analysis. The measured spectra were accurately analyzed by HYPERMET-PC. Prompt γ-ray energies and associated γ-ray production cross-sections have been determined by internal standardization. The resulting catalog contains prompt γ-ray data from neutron capture and other reactions such as (n,α), and decay γ-ray data from short-lived reaction products. Data have been measured for nearly all stable elements, from hydrogen to uranium. Generally, data for several isotopes are given, to enable isotopic analysis as well. The whole library, including elemental spectra, will be available as a book.
