100 mu-g/cm2 enriched (83.2%) Nd-143. 3027700100012 METHOD An experimental set up was used in which only the 3027700100013 target is situated in the neutron beam while the detec-3027700100014 tor is placed some distance aside. 3027700100015 DETECTOR (TELES,SIBAR,SIBAR) Telescope consisting of 2 silicon 3027700100016 surface barrier detectors = 3027700100017 .'dE/dx', 11 mu thick, 3027700100018 .'E', 100 mu thick. 3027700100019 The following resolution was obtained = 3027700100020 .85 keV for alpha-particles from americium, 3027700100021 .100-130 keV for alpha particles from neutron cap- 3027700100022 ture. 3027700100023 Energy and efficiency calibration were based on the 3027700100024 alpha spectrum from Sm-149(n,alpha). 3027700100025 PART-DET (A) Alphas 3027700100026 STATUS (APRVD)
