C2519 1 15 DETECTOR (MAGSP) Charged particles were momentum analyzed C2519 1 16 using S800 spectrograph C2519 1 17 (SCIN) Event-by-event identification of the incoming C2519 1 18 projectiles and outgoing reaction products was C2519 1 19 performed using plastic timing scintillators and the C2519 1 20 S800 focal-plane detector C2519 1 21 (MWDC,IOCH,SCIN) Focal Plane Detector Array of the C2519 1 22 S800 Spectrometer consists of a series of two x/y C2519 1 23 Position Sensitive Cathode Readout Drift Counters C2519 1 24 separated by 1 m, a segmented Ionization Chamber that C2519 1 25 is 41 cm deep and three scintillators that are 5, 10 C2519 1 26 and 20 cm thick, respectively. All detectors have an C2519 1 27 active area of 30 cm x 59 cm. C2519 1 28 (CSICR) Secondary target was surrounded by CAESAR, a C2519 1 29 high-efficiency array consisting of 192 CsI(Na) C2519 1 30 scintillators,to measure deexcitation gamma rays from C2519 1 31 the reaction channels of interest. C2519 1 32 METHOD (EDE,TOF) C2519 1 33 CORRECTION Gamma ray energies were corrected for Doppler shift C2519 1 34 INC-SOURCE (KINDT) A secondary beam including 24Mg (54.5%), 25Al C2519 1 35 (29.5%) , and 26Si (13.5%) was produced by impinging C2519 1 36 the 150-MeV/u 36Ar primary beam on a 550-mg/cm2 9Be C2519 1 37 target at the midacceptance position of the A1900 C2519 1 38 fragment separator.
