SAMPLE 252Cf electro-deposited on Au planchet covered with 3152300100013
VYNS film. 3152300100014
Fission fragments could pass through film. 3152300100015
Fission fragments were collected on sodium acetate 3152300100016
salt pellets with mass thickness 70-90 mg/cm2. 3152300100017
METHOD (CHSEP) Pellets were dissolved in hot basic solution 3152300100018
containing iodine carrier and a little hold-back 3152300100019
carrier of tellurium. 3152300100020
After completion of separation, iodine was oxidized, 3152300100021
then extracted and after further chemical procedures 3152300100022
collected on a teflon disc, dried, mounted and 3152300100023
counted. 3152300100024
(GSPEC) 133I (530 keV peak) was counted, 135I was 3152300100025
used as intrinsic monitor for the chemical yield. 3152300100026
Spectra were taken at different separation times. 3152300100027
DETECTOR (NAICR) Low-background NaI(Tl) scintillation detector 3152300100028
coupled to multichannel analyzer. 3152300100029
ANALYSIS (DECAY) Spectra taken at different delay (separation) 3152300100030
times were used to obtain the parameters of the 3152300100031
equations for the growth (from 133mTe and 133gTe) 3152300100032
and the decay of 133I, and hence for the fractional 3152300100033
yields of 133mTe and 133gTe. 3152300100034
The equations were solved in an iteration process. 3152300100035

ASSUMED (ASSUM,98-CF-252(0,F)51-SB-133,CUM,FY,,FRC) 3152300100039
CORRECTION Corrected for 3152300100040
- chemical yield, 3152300100041
- interfering gamma-peaks of 135mXe and 135gXe, 3152300100042
- efficiencies of counters. 3152300100043
ERR-ANALYS No information on the source of the uncertainty. 3152300100044
Compiler's comment: The total error is probably 3152300100045
resulting from the iteration process employed to 3152300100046
obtain fractional yields from activities. 3152300100047
