TITLE Determination of independent yields of I131 and I133 3094600100006
in thermal neutron fission of 235U by selective recoil 3094600100007
labelling 3094600100008
FACILITY No information given, but the compiler assumes that the3094600100009
irradiations were done at the IRR-1 swimming pool type 3094600100010
reactor at the Soreq Nuclear Research Center. 3094600100011
METHOD (RCHEM) 2 methods were employed: 3094600100012
1) The apparent direct yields of I-133,I-134 and I-1353094600100013
were obtained by selective labelling; 3094600100014
2) the respective cumulative yields by conventional 3094600100015
wet radiochemistry. 3094600100016
(GSPEC) 3094600100017
ANALYSIS The amounts obtained by method 1) were expressed as 3094600100018
fractions of those obtained by method 2), giving the 3094600100019
apparent fractional independent yield. The real 3094600100020
independent yields were obtained by extrapolation of 3094600100021
the apparent fractional yields to zero time after 3094600100022
irradiation. 3094600100023

ANALYSIS The assumed values were used for conversion of the 3094600300012
measured values to independent fission yields. 3094600300013
Compilers note: since the yields were obtained from 3094600300014
relative activities of iodine fission product isotopes,3094600300015
all assumed values were used for the complete 3094600300016
analysis of raw data. 3094600300017
COMMENT by commpiler: apparently was the independent yield of 3094600300018
I-134 used to normalize the measured relative direct 3094600300019
yields obtained by method 1). It was calculated from 3094600300020
the fractional independent yield given by Wahl 3094600300021
(ASSUM3) and the I-134 cumulative yield by Katcoff. 3094600300022
