C169800100013 INSTITUTE (1USABRK,1USAORU,1USAUCX,2UK SUR,2SWDUPP,2SWTPSI) C169800100014 FACILITY (CYCLO,1USABRK) Berkeley gas-filled separator (BGS) at C169800100015 the LBNL 88-inch cyclotron facility. C169800100016 SAMPLE The 208Pb target consisted of nine arc shaped segments,C169800100017 each with a 500-microg/cm2 thick lead layer C169800100018 sandwiched between layers of carbon with thicknesses C169800100019 of 40 microg/cm2 (facing the beam) and 2 microg/cm2. C169800100020 These segments were mounted around the periphery of a C169800100021 14-inch diameter wheel which was rotated to minimize C169800100022 thermal stress on the target from beam heating. C169800100023 DETECTOR (SISD,PGAC) Two silicon p-i-n detectors (mounted at C169800100024 ~27 degrees with respect to the incident beam) C169800100025 monitored the product of beam intensity and target C169800100026 thickness by detecting beam particles that were C169800100027 elastically scattered from the target. Parallel Plate C169800100028 Avalanche Counters (PPACs) were provided by Michigan C169800100029 State University. C169800100030 METHOD (ASPEC,ASEP,TOF) The beam energies at the center of C169800100031 the target were 306.7, 309.2, and 312.8 MeV. The BGS C169800100032 spatially separated the recoiling fusion evaporation C169800100033 residues (EVR's, E~70 MeV) in flight from both beam C169800100034 particles and transfer reaction products on the basis C169800100035 of their differing magnetic rigidities within the C169800100036 separator's 0.88-torr helium atmosphere. At the BGS C169800100037 focal plane, the EVR's were deposited into a C169800100038 300-microm thick passivated ion implanted silicon C169800100039 detector with an active area of 116 mm (horizontal) x C169800100040 58 mm (vertical). Two chains of time- and position- C169800100041 correlated events were observed. Each chain consisted C169800100042 of the implantation of an evaporation residue C169800100043 followed by the emission of alpha particles. C169800100044 ANALYSIS (PES) The cross sections were calculated assuming C169800100045 their values to be constant for all beam energies C169800100046 throughout the target thickness.
