Chemical purity was 99.9%. 3099400100011 FACILITY (VDG) 3099400100012 INC-SOURCE (P-LI7,P-T) Neutrons, with an energy between 29 and 23 3099400100013 keV, and 215 and 1100 keV respectively, were produced 3099400100014 by bombarding the targets with 2.5 MeV protons. Neutron3099400100015 energy was further selected by choice of angle of 3099400100016 neutron emission with respect to the incident proton 3099400100017 beam. 3099400100018 METHOD (ACTIV) 3099400100019 DETECTOR (HPGE) 3099400100020 MONITOR (79-AU-197(N,G)79-AU-198,,SIG) Cross-section from 3099400100021 ENDF/B-V.
