Abstract

The Westcott convention was introduced in the early 1990s in k 0-NAA to allow the analysis of nuclides whose thermal neutron capture cross-sections do not follow the “1/v”-law, so called “non-1/v” nuclides. Most affected nuclides are Lu-176, Eu-151 and Yb-169. Westcott introduced a neutron temperature dependent “g(T n )-factor” for the activation by thermal neutrons. Recently the extended Høgdahl convention was introduced in k 0-NAA for “non-1/v” nuclides using the same factor, emphasizing the interest in the analysis using these nuclides. This paper reviews most publications on “g(T n )-factors” for NAA and provides new factors based on the most recent evaluated nuclear database ENDF/B-VII.1.
