摘要：

A new instrument for fast neutron gamma spectroscopy has been installed and tested at the Forschungsneutronenquelle Heinz Maier-Leibnitz of the MLZ in Garching. A beam with the flux of about 10(8) cm(-2) s(-1) fission neutrons is available to irradiate small samples to study inelastic neutron scattering reactions in materials. A number of relevant elements have been investigated and new gamma lines were identified in comparison to existing data libraries. The method seems to be linear with respect to measurement time and sample mass. A particular advantage of fast neutron PGAA compared to thermal neutron PGAA appears in the analysis of materials with high thermal capture cross sections.
