Each detector was located 2.4 cm from the 1461300100014 source foil. The sensitive area of each fragment 1461300100015 detector was reduced to the center 254 mm2 by the use 1461300100016 of aluminum apertures to eliminate edge effects in the 1461300100017 fragment spectrum. 1461300100018 (NAICR) The x-ray detector was a 1-mm-thick NaI(Tl) 1461300100019 scintillator mounted on an RCA 6342A phototube, covered1461300100020 by a 0.13-mm-thick Be window and presenting an active 1461300100021 circular area of 3.37 cm2 at 5 cm from the source foil.1461300100022 The detector was restricted by a cylindrical copper 1461300100023 collimator to view the first centimeter of fragment 1461300100024 path. 1461300100025 SAMPLE (92-U-235,ENR=0.93) An uranium oxide deposit enriched 1461300100026 to 93% U235, covering a circular area of 1.1 cm2 and 1461300100027 approximately 70 mu-g/cm2 thick, prepared by vacuum 1461300100028 evaporation of UO2 onto a nickel backing 90 mu-g/cm2 1461300100029 thick. 1461300100030 ERR-ANALYS (DATA-ERR) No information on source of uncertainties 1461300100031 HISTORY (20200304C) OG. 1461300100032 ENDBIB 30 0 1461300100033 COMMON 1 3 1461300100034 EN-DUMMY 1461300100035 EV 1461300100036 0.0253 1461300100037 ENDCOMMON 3 0 1461300100038 ENDSUBENT 37 0 1461300199999 SUBENT 14613002 20200304 14671461300200001 BIB 2 3 1461300200002 REACTION (92-U-235(N,F)MASS,PRE,FY,,SPA) 1461300200003 STATUS (CURVE) Fig.3 in Phys.Rev.,188,1909,1969 digitized 1461300200004 by GSYS2.4.7. 1461300200005 ENDBIB 3 0 1461300200006 NOCOMMON 0 0 1461300200007 DATA 3 44 1461300200008 MASS DATA DATA-ERR 1461300200009 NO-DIM PC/FIS PC/FIS 1461300200010 75. 0.0853 1461300200011 76. 0.0711 1461300200012 77. 0.0711 1461300200013 78. 0.0995 1461300200014 79. 0.1422 1461300200015 80. 0.2133 1461300200016 81. 0.2701 1461300200017 82. 0.3697 1461300200018 83. 0.5403 1461300200019 84. 0.7678 1461300200020 85. 1.1516 1461300200021 86. 1.4218 1461300200022 87. 2.0189 1461300200023 88. 2.5592 1461300200024 89. 3.4122 1461300200025 90. 4.0520 1461300200026 91. 4.6065 1461300200027 92. 5.2037 1461300200028 93. 5.9003 1461300200029 94. 6.1562 1461300200030 95. 6.1989 1461300200031 96. 5.9998 0.1280 1461300200032 97. 6.1136 1461300200033 98. 5.7439 1461300200034 99. 6.0567 1461300200035 100. 5.7866 1461300200036 101. 5.3885 1461300200037 102. 4.7913 1461300200038 103. 4.3364 1461300200039 104. 3.5118 1461300200040 105. 2.5165 1461300200041 106. 1.8056 1461300200042 107. 1.1943 1461300200043 108. 0.7109 1461300200044 109. 0.3839 1461300200045 110. 0.1990 1461300200046 111. 0.1137 1461300200047 112. 0.0853 1461300200048 113. 0.0569 1461300200049 114. 0.0569 1461300200050 115. 0.0569 1461300200051 116. 0.0427 1461300200052 117. 0.0569 1461300200053 118. 0.0427 1461300200054 ENDDATA 46 0 1461300200055 ENDSUBENT 54 0 1461300299999 ENDENTRY 2 0 1461399999999
