Five or six such pellets comprise the 3093800100012 cylindrical experimental target. 3093800100013 In case of Ni, a stack of alternate Ni and Al foils 3093800100014 are used as the target. 3093800100015 FACILITY (VDG,3INDBHU) 3093800100016 INC-SOURCE (D-T) At 300 keV deuteron energy 3093800100017 MONITOR (13-AL-27(N,A)11-NA-24,,SIG) 3093800100018 Monitor value not given. 3093800100019 METHOD (ACTIV) 3093800100020 PART-DET (DG) 3093800100021 CORRECTION Relative efficiency measurement are made, using a thin 3093800100022 uniform disc of standard Eu-152 source, having the same3093800100023 diam. as the target. <>. 3093800100024 Using such a technique the self-absorption and self- 3093800100025 scattering effects due to the target are fully taken 3093800100026 into account, experimentally. 3093800100027 DETECTOR (HPGE) With resolution of 1.78 keV FWHM for 1.33 MeV g.3093800100028 ERR-ANALYS (ERR-T) The errors quoted on the cross section 3093800100029 comprise : 3093800100030 (ERR-S,1.,3.)
