Timing information 1442000100026 was used for fragment velocity determination. 1442000100027 Position information was used for corrections of path 1442000100028 length for fragments traveling at angles relative to 1442000100029 central trajectory. 1442000100030 (IOCH) Energy of the fission fragment was measured 1442000100031 in an ionization chamber. 1442000100032 METHOD (TOF,COINC) Fragment velocity was measured using time 1442000100033 of flight. Triple coincidence of two MCP detectors and 1442000100034 ionization chamber was required for each fragment. 1442000100035 INC-SOURCE (CF252) 1442000100036 ERR-ANALYS (DATA-ERR) No information given 1442000100037 HISTORY (20150720C) Compiled by S.H. 1442000100038 ENDBIB 36 0 1442000100039 NOCOMMON 0 0 1442000100040 ENDSUBENT 39 0 1442000199999 SUBENT 14420002 20150720 14091442000200001 BIB 2 3 1442000200002 REACTION (98-CF-252(0,F)MASS,SEC,FY) 1442000200003 STATUS (CURVE) Data taken from fig. 12 of the reference 1442000200004 Waiting for data from author 1442000200005 ENDBIB 3 0 1442000200006 NOCOMMON 0 0 1442000200007 DATA 3 93 1442000200008 MASS DATA DATA-ERR 1442000200009 NO-DIM PC/FIS PC/FIS 1442000200010 80.0 1.27E-02 1442000200011 81.0 1.64E-02 1442000200012 82.0 1.27E-02 1442000200013 83.0 3.88E-02 1442000200014 84.0 4.26E-02 1442000200015 85.0 3.88E-02 1442000200016 86.0 1.06E-01 1442000200017 87.0 1.25E-01 1442000200018 88.0 1.84E-01 1442000200019 89.0 2.93E-01 1442000200020 90.0 3.79E-01 1442000200021 91.0 4.87E-01 3.73E-03 1442000200022 92.0 5.80E-01 1442000200023 93.0 7.33E-01 1442000200024 94.0 9.39E-01 1442000200025 95.0 1.10E+00 1442000200026 96.0 1.32E+00 1442000200027 97.0 1.57E+00 1442000200028 98.0 1.87E+00 1442000200029 99.0 2.40E+00 1442000200030 100.0 2.90E+00 1442000200031 101.0 3.50E+00 6.72E-02 1442000200032 102.0 4.05E+00 5.98E-02 1442000200033 103.0 4.85E+00 7.84E-02 1442000200034 104.0 5.54E+00 6.35E-02 1442000200035 105.0 6.11E+00 6.72E-02 1442000200036 106.0 6.43E+00 5.98E-02 1442000200037 107.0 6.26E+00 7.84E-02 1442000200038 108.0 6.25E+00 7.47E-02 1442000200039 109.0 5.84E+00 8.96E-02 1442000200040 110.0 5.59E+00 6.35E-02 1442000200041 111.0 5.36E+00 6.72E-02 1442000200042 112.0 4.65E+00 7.10E-02 1442000200043 113.0 4.37E+00 7.47E-02 1442000200044 114.0 3.86E+00 5.23E-02 1442000200045 115.0 3.42E+00 1442000200046 116.0 2.78E+00 1442000200047 117.0 2.12E+00 1442000200048 118.0 1.60E+00 1442000200049 119.0 1.08E+00 1442000200050 120.0 6.25E-01 1442000200051 121.0 3.79E-01 1442000200052 122.0 1.77E-01 1442000200053 123.0 1.21E-01 1442000200054 124.0 1.06E-01 1442000200055 125.0 1.21E-01 1442000200056 126.0 1.62E-01 1442000200057 127.0 2.03E-01 1442000200058 128.0 3.49E-01 1442000200059 129.0 6.77E-01 1442000200060 130.0 1.19E+00 1442000200061 131.0 1.87E+00 1442000200062 132.0 2.72E+00 1442000200063 132.9 3.62E+00 6.72E-02 1442000200064 134.0 4.03E+00 1442000200065 135.0 4.31E+00 1442000200066 136.0 4.75E+00 7.47E-02 1442000200067 137.0 5.19E+00 6.72E-02 1442000200068 138.0 5.47E+00 6.35E-02 1442000200069 139.0 5.71E+00 8.59E-02 1442000200070 140.0 5.92E+00 6.35E-02 1442000200071 141.0 6.08E+00 1442000200072 142.0 6.27E+00 6.72E-02 1442000200073 142.9 6.18E+00 7.47E-02 1442000200074 144.0 5.70E+00 7.84E-02 1442000200075 145.0 4.86E+00 7.47E-02 1442000200076 146.0 4.36E+00 6.72E-02 1442000200077 147.0 3.57E+00 6.35E-02 1442000200078 148.0 3.09E+00 1442000200079 149.0 2.53E+00 1442000200080 150.0 2.09E+00 1442000200081 151.0 1.72E+00 1442000200082 152.0 1.54E+00 1442000200083 153.0 1.16E+00 1442000200084 154.0 8.94E-01 1442000200085 155.0 7.60E-01 1442000200086 156.0 5.77E-01 1442000200087 157.0 5.62E-01 1442000200088 158.0 4.65E-01 1442000200089 159.0 3.67E-01 1442000200090 160.0 3.11E-01 1442000200091 161.0 2.18E-01 1442000200092 162.0 1.73E-01 1442000200093 163.0 1.32E-01 1442000200094 164.0 1.17E-01 1442000200095 165.0 1.10E-01 1442000200096 166.0 5.00E-02 1442000200097 167.0 3.88E-02 1442000200098 168.0 3.88E-02 1442000200099 169.0 1.64E-02 1442000200100 170.0 2.02E-02 1442000200101 171.0 1.64E-02 1442000200102 172.0 1.27E-02 1442000200103 ENDDATA 95 0 1442000200104 ENDSUBENT 103 0 1442000299999 ENDENTRY 2 0 1442099999999
