The V- and O133000100014 Lu-metal sheets and the Pd-V(10%) and Pd-Lu(10%) alloysO133000100015 were 0.5 and 0.4-mm thick, respectively. The VO(2) or O133000100016 Lu(2)O(3) powder was pressed into a cyllindrical hole, O133000100017 28-mm diameter, 5-mm deep, of a Cu-backing with a O133000100018 thickness of about 5-mm. O133000100019 DETECTOR (D4PI) The neutron yields were measured using a 4-pi O133000100020 detector, consisting of eight He-3 filled proportional O133000100021 counters, embedded in a polyethylene-cylinder moderatorO133000100022 with a central bore hole to install the target. The O133000100023 spectra of the 8-counters were summed, dead time O133000100024 effects were kept below 1%. The neutron efficiency as O133000100025 a function of neutron energy was calculated and tested O133000100026 using a calibrated Cf-252 source. The efficiency variesO133000100027 from 29% to 27% for both (p.n) reactions over the O133000100028 Energy range. O133000100029 FACILITY (DYNAM,2GERBOC) The 4-mv tandem accelerator.
