Appr. monoenergetic 3145400100019 neutrons of 9.5 and 9.9 MeV were produced. The 3145400100020 target-sample distances were resp. 0.8 and 1.2 cm. 3145400100021 SAMPLE The samples ( 2 cm in diameter) were arranged in the 3145400100022 following order: Au(0.1 mm, 1.5 g), Ag(0.5 mm, 1.5 g), 3145400100023 Au, HfO2(5.1 mm, 8.2 g), Au, TbO3(2.0 mm, 2.58 g), Au, 3145400100024 Eu2O3(2.45 mm, 1.5 g), Au, Ni(0.2 mm, 0.5 g), 3145400100025 Al(0.4 mm, 0.34 g), Au, Ni, Re(0.1 mm, 0.6 g), Ni, 3145400100026 Zn(0.45 mm, 1.0 g), Ni.
