FACILITY Gammasphere. 1454500100021
METHOD (COINC,GSPEC) The triple gamma coincidence technique 1454500100022
with Gammasphere. 1454500100023
DETECTOR (GE-IN) 72 Compton suppressed Ge detectors 1454500100024
(TELES,SI,SISD) The energy spectrum of charged 1454500100025
particles was measured by using two deltaE-E Si 1454500100026
detector telescopes installed at the center of the 1454500100027
Gammasphere array at Argonne National Laboratory. 1454500100028
Each deltaE-E telescope included one deltaE detector 1454500100029
(of 15 mu-m thickness and 10x10 mm2 area) and one 1454500100030
strip detector. The strip detectors were 400 mu-m and 1454500100031
60x60 mm2 in thickness and area, respectively and had 1454500100032
29 strips. With the position resolution of the strip 1454500100033
detector (4 mm wide strips and 1 mm resolution along 1454500100034
each strip) , the deltaE-E telescopes provided 1454500100035
unambiguous Z and A identification for all the light 1454500100036
charged particles of interest. The energy calibration 1454500100037
of the telescopes was performed with 224Ra and 228Th 1454500100038
radioactive sources. This calibration automatically 1454500100039
takes the presence of the Mylar foil into account. A 1454500100040
software correction was applied for the energy loss 1454500100041
in the Au foil. 1454500100042
SAMPLE The 252Cf source with a strength of the order of 30 1454500100043
mu-Ci was sandwiched between two Au foils, each 19 1454500100044
mg/cm2 in thickness. These foils were used to stop 1454500100045
the fission fragments so that problems associated 1454500100046
with the Doppler shift of prompt fission gamma-rays 1454500100047
were minimized. In addition, on each side of the 1454500100048
source a 0.84 mg/cm2 Mylar foil was added to provide 1454500100049
full absorption of a particles emitted in the 1454500100050
radioactive decay of 252Cf. 1454500100051
