The strip detectors were 400 mu-m and 14545 1 31 60x60 mm2 in thickness and area, respectively and had 14545 1 32 29 strips. With the position resolution of the strip 14545 1 33 detector (4 mm wide strips and 1 mm resolution along 14545 1 34 each strip) , the deltaE-E telescopes provided 14545 1 35 unambiguous Z and A identification for all the light 14545 1 36 charged particles of interest. The energy calibration 14545 1 37 of the telescopes was performed with 224Ra and 228Th 14545 1 38 radioactive sources. This calibration automatically 14545 1 39 takes the presence of the Mylar foil into account. A 14545 1 40 software correction was applied for the energy loss 14545 1 41 in the Au foil. 14545 1 42 SAMPLE The 252Cf source with a strength of the order of 30 14545 1 43 mu-Ci was sandwiched between two Au foils, each 19 14545 1 44 mg/cm2 in thickness. These foils were used to stop 14545 1 45 the fission fragments so that problems associated 14545 1 46 with the Doppler shift of prompt fission gamma-rays 14545 1 47 were minimized. In addition, on each side of the 14545 1 48 source a 0.84 mg/cm2 Mylar foil was added to provide 14545 1 49 full absorption of a particles emitted in the 14545 1 50 radioactive decay of 252Cf. 14545 1 51 STATUS (TABLE) Table 3 in the main ref. 14545 1 52 HISTORY (20190812C) OG. 14545 1 53 ENDBIB 51 0 14545 1 54 NOCOMMON 0 0 14545 1 55 ENDSUBENT 54 0 14545 199999 SUBENT 14545002 20190812 145714545 2 1 BIB 4 4 14545 2 2 REACTION (98-CF-252(0,F)2-HE-4,TER,KE) 14545 2 3 MISC-COL (MISC) FWHM of measured energy distribution 14545 2 4 ERR-ANALYS (DATA-ERR) No information on source of uncertainties. 14545 2 5 STATUS (TABLE) Table 3 in the main ref. 14545 2 6 ENDBIB 4 0 14545 2 7 NOCOMMON 0 0 14545 2 8 DATA 6 1 14545 2 9 DATA +DATA-ERR -DATA-ERR MISC +MISC-ERR -MISC-ERR 14545 2 10 MEV MEV MEV MEV MEV MEV 14545 2 11 16.0 1.0 0.5 7.4 0.4 0.8 14545 2 12 ENDDATA 3 0 14545 2 13 ENDSUBENT 12 0 14545 299999 SUBENT 14545003 20190812 145714545 3 1 BIB 4 4 14545 3 2 REACTION (98-CF-252(0,F)2-HE-5,TER,KE) 14545 3 3 MISC-COL (MISC) FWHM of measured energy distribution 14545 3 4 ERR-ANALYS (DATA-ERR) No information on source of uncertainties. 14545 3 5 STATUS (TABLE) Table 3 in the main ref. 14545 3 6 ENDBIB 4 0 14545 3 7 NOCOMMON 0 0 14545 3 8 DATA 6 1 14545 3 9 DATA +DATA-ERR -DATA-ERR MISC +MISC-ERR -MISC-ERR 14545 3 10 MEV MEV MEV MEV MEV MEV 14545 3 11 13.9 1.1 4.3 7.4 0.4 0.8 14545 3 12 ENDDATA 3 0 14545 3 13 ENDSUBENT 12 0 14545 399999 SUBENT 14545004 20190812 145714545 4 1 BIB 3 8 14545 4 2 REACTION ((98-CF-252(0,F)2-HE-4,TER,FY)/ 14545 4 3 ((98-CF-252(0,F)2-HE-4,TER,FY)+ 14545 4 4 (98-CF-252(0,F)2-HE-5,TER,FY))) 14545 4 5 ERR-ANALYS (DATA-ERR) No information on source of uncertainties. 14545 4 6 STATUS (TABLE) Table 3 in the main ref. 14545 4 7 (DEP,14545002) 14545 4 8 (DEP,14545003) 14545 4 9 (COREL,14545005) 14545 4 10 ENDBIB 8 0 14545 4 11 NOCOMMON 0 0 14545 4 12 DATA 3 1 14545 4 13 DATA -DATA-ERR +DATA-ERR 14545 4 14 NO-DIM NO-DIM NO-DIM 14545 4 15 0.796 0.244 0.120 14545 4 16 ENDDATA 3 0 14545 4 17 ENDSUBENT 16 0 14545 499999 SUBENT 14545005 20190812 145714545 5 1 BIB 3 8 14545 5 2 REACTION ((98-CF-252(0,F)2-HE-5,TER,FY)/ 14545 5 3 ((98-CF-252(0,F)2-HE-4,TER,FY)+ 14545 5 4 (98-CF-252(0,F)2-HE-5,TER,FY))) 14545 5 5 ERR-ANALYS (DATA-ERR) No information on source of uncertainties. 14545 5 6 STATUS (TABLE) Table 3 in the main ref. 14545 5 7 (DEP,14545002) 14545 5 8 (DEP,14545003) 14545 5 9 (COREL,14545004) 14545 5 10 ENDBIB 8 0 14545 5 11 NOCOMMON 0 0 14545 5 12 DATA 3 1 14545 5 13 DATA -DATA-ERR +DATA-ERR 14545 5 14 NO-DIM NO-DIM NO-DIM 14545 5 15 0.204 0.029 0.219 14545 5 16 ENDDATA 3 0 14545 5 17 ENDSUBENT 16 0 14545 599999 ENDENTRY 5 0 1454599999999
