Measured target 1463100100018 thicknesses ranged from 118 to 142 microg/cm2. Each 1463100100019 foil was mounted on a target holder frame, and ten of 1463100100020 the target holder frames were mounted in the LIM 1463100100021 Target System, with a spacing of approximately 1 cm 1463100100022 between the targets. A 25-microm beryllium foil 1463100100023 served as the volume limiting foil (which confines 1463100100024 the gas volume downstream of the last target to the 1463100100025 same as that for the rest of the targets) for the LIM 1463100100026 Target System, and another 25-microm beryllium foil 1463100100027 upstream of the targets served as the vacuum window 1463100100028 for the system. 1463100100029 DETECTOR (SIBAR) A light tight transmission-mounted 300-mm 1463100100030 silicon-surface barrier detector. 1463100100031 METHOD (CHSEP,XSPEC) Radiochemical and K X-ray measurements. 1463100100032 Two different chemical separations were performed on 1463100100033 the reaction products of these irradiations. The 1463100100034 first separation was designed to determine the 1463100100035 elemental assignment of the fission activity, the 1463100100036 second was used to produce an americium sample 1463100100037 suitable for measurement of the plutonium K x-rays 1463100100038 from the EC decay of 232Am. 1463100100039 ERR-ANALYS (DATA-ERR) No details on sources of uncertainties. 1463100100040 DECAY-DATA (95-AM-232,1.31MIN) Measured by authors. 1463100100041 HISTORY (20200323C) BP 1463100100042 ENDBIB 40 0 1463100100043 NOCOMMON 0 0 1463100100044 ENDSUBENT 43 0 1463100199999 SUBENT 14631002 20200323 14671463100200001 BIB 2 5 1463100200002 REACTION 1(95-AM-232(0,F),PRE,AKE,LF+HF,MSC) 1463100200003 Electron-capture delayed fission 1463100200004 2(95-AM-232(0,F),SEC,AKE,LF+HF,MSC) 1463100200005 Electron-capture delayed fission 1463100200006 STATUS (TABLE) Table I, page 1484. 1463100200007 ENDBIB 5 0 1463100200008 NOCOMMON 0 0 1463100200009 DATA 4 1 1463100200010 DATA 1DATA-ERR 1DATA 2DATA-ERR 2 1463100200011 MEV MEV MEV MEV 1463100200012 174.0 5.0 173.0 5.0 1463100200013 ENDDATA 3 0 1463100200014 ENDSUBENT 13 0 1463100299999 ENDENTRY 2 0 1463199999999
