The distances from the 3278800100017 fission source to F1 and F2 were 6 and 4 cm, 3278800100018 respectively. Both surface barrier detectors with 3278800100019 diameter 20 mm were collimated down to 16 mm in 3278800100020 diameter to avoid the edge effect. 3278800100021 (STANK) A cylindrical liquid scintillator (diameter 3278800100022 10 cm x 5 cm) held with wire 46 cm behind F1 served 3278800100023 as a neutron detector. 3278800100024 (HPGE) A high-purity germanium detector behind F2, 3278800100025 with efficiency 60% relative to a NaI(Tl) gamma-ray 3278800100026 detector, was placed 36 cm from F2. The HPGe detector 3278800100027 was shielded by lead bricks. Separate data were taken 3278800100028 with the HPGe detector in locations 0 and 90 degree. 3278800100029 METHOD The assignment of individual fragment gamma-ray 3278800100030 multiplicities were made by employing the Doppler 3278800100031 shift method. 3278800100032 (COINC) The neutron multiplicity was determined by 3278800100033 comparing the number of coincident fission neutrons 3278800100034 to the number of fissions, obtained from the 3278800100035 detection of F1 or F2. 3278800100036 CORRECTION Corrections due to neutron and gamma-ray scattering 3278800100037 and absorption were carried out during the data 3278800100038 analysis 3278800100039 ERR-ANALYS (ERR-T) The total uncertainties were calculated from 3278800100040 statistical errors together with the systematic errors.3278800100041 (ERR-1) The contributions of extrapolation of the gamma3278800100042 -ray pulse height spectrum below the discrimination 3278800100043 level is around 0.8%. 3278800100044 (ERR-2) Errors of nuclear data used for corrections by 3278800100045 Monte Carlo simulation (~4%) 3278800100046 STATUS (TABLE) Data were obtained from Taofeng Wang. 3278800100047 HISTORY (20190709R) Data received from Taofeng Wang 3278800100048 (20191011C) Compiled by WANG Jimin (CNDC) . 3278800100049 (20220627A) VT.
