L017900100016 #doi:10.5506/APhysPolB.44.643 L017900100017 FACILITY (ESTRG,1USATNL) Experiment performed at the HIgS L017900100018 facility at TUNL L017900100019 SAMPLE Target consisted of 23 electrolytically deposited L017900100020 238U(O)2 targets, each with thickness of 2 mg/cm2 L017900100021 DETECTOR (PPAC) Array of parallel plate avalanche counters L017900100022 containing UO2 targets was used to detect both L017900100023 fission fragments in coincidence to reduce background L017900100024 from alpha particles. L017900100025 METHOD (COINC) Coincidence was required to detect both L017900100026 fission fragments L017900100027 INC-SOURCE (LCS) Nearly monoenergetic gamma-rays were produced L017900100028 by Compton backscattering of photons of the L017900100029 free-electron laser. Beams of circularly polarized L017900100030 gamma rays with energies between 4.5 and 6 MeV L017900100031 were used with energy spreads of 150 - 200 keV and L017900100032 spectral flux of about 1E+2 photons/(eV s) L017900100033 HISTORY (20130509C) Compiled by S.H.
