The real 3094600100020 independent yields were obtained by extrapolation of 3094600100021 the apparent fractional yields to zero time after 3094600100022 irradiation. 3094600100023 HISTORY (19881017T) Automatic conversion from Rider file 3094600100024 Reference 66YOS1 3094600100025 (20010418A) ML: Corrections and addition of information3094600100026 from the publication.

It was calculated from 3094600300020 the fractional independent yield given by Wahl 3094600300021 (ASSUM3) and the I-134 cumulative yield by Katcoff. 3094600300022 STATUS Data from text on page 64 of progress report IA-1128. 3094600300023 ENDBIB 21 0 3094600300024 COMMON 2 3 3094600300025 ASSUM2 2ASSUM3 3 3094600300026 PC/FIS NO-DIM 3094600300027 7.8 0.12 3094600300028 ENDCOMMON 3 0 3094600300029 DATA 5 2 3094600300030 ELEMENT MASS ISOMER DATA ASSUM1 1 3094600300031 NO-DIM NO-DIM NO-DIM PC/FIS PC/FIS 3094600300032 53. 133. 0. 0.8 6.9 3094600300033 53. 135. 2.6 6.1 3094600300034 ENDDATA 4 0 3094600300035 ENDSUBENT 34 0 3094600399999 ENDENTRY 3 0 3094699999999
