INC-SOURCE (BRST) Electron beam impinged on thick Ta target, the M075900100012
Al cylinder stops the residual electrons. M075900100013
SAMPLE Targets of 238U (400 g) and 235U(11 g). M075900100014
PART-DET (DN) M075900100015
METHOD (EXTB,SITA) M075900100016
DETECTOR (HE3SP) Twelve 3He gas counters inside CH2 ring. M075900100017
ANALYSIS (DECAY) The number of delayed neutrons (DN) was M075900100018
obtained as the integral of DN decay spectrum (time M075900100019
dependent yield measured) corrected for background, M075900100020
detector efficiency and contribution of (n,fiss) M075900100021
reactions. The number of fissions (induced by M075900100022
photons and neutrons) was evaluated using the MCNPX M075900100023
transport code. M075900100024
ERR-ANALYS (ERR-S) Statistical errors only: the systematic M075900100025
uncertainty due to the electron charge measurements M075900100026
is difficult to evaluate and has not yet taken into M075900100027
account. M075900100028
