For Rh-105 the grow-in 3094500100013 time was 10 days. The grow-in times correspond to 3094500100014 about 7 times the rspective half-lives, and it was 3094500100015 was assumed that equilibrium activity was reached. 3094500100016 DETECTOR (GEMUC) Rectangular perspex gas flow Geiger Mueller 3094500100017 counter with background rate of 1 cpm. 3094500100018 ANALYSIS The fission yield was calculated from the fission 3094500100019 product equilibrium activity and the U-238 spontaneous 3094500100020 fission rate. 3094500100021 STATUS Data taken from J.Inorg.Nucl.Chem. 27(1965)2679 3094500100022 HISTORY (19881017T) automatic conversion from Rider file, 3094500100023 reference 65RAO1 3094500100024 (20010417A) Subentry 1 revised by ML from paper 3094500100025 ENDBIB 23 0 3094500100026 NOCOMMON 0 0 3094500100027 ENDSUBENT 26 0 3094500199999 SUBENT 30945002 19920609 00003094500200001 BIB 1 1 3094500200002 REACTION (92-U-238(0,F)ELEM/MASS,CUM,FY) 3094500200003 ENDBIB 1 0 3094500200004 NOCOMMON 0 0 3094500200005 DATA 5 2 3094500200006 ELEMENT MASS ISOMER DATA DATA-ERR 3094500200007 NO-DIM NO-DIM NO-DIM PC/FIS PC/FIS 3094500200008 44. 105. 0.634 0.127 3094500200009 45. 105. 0. 0.688 0.138 3094500200010 ENDDATA 4 0 3094500200011 ENDSUBENT 10 0 3094500299999 ENDENTRY 2 0 3094599999999
