Radioactive Ion Beams in Brazil (RIBAS) D064500100020
INC-SOURCE A primary 7Li3+ beam with energies around 25 MeV and D064500100021
a beam current of 300 nAe hits the primary 9Be D064500100022
target. The 6He beam is produced by one-proton D064500100023
removal from 7Li in the 9Be(7Li,6He)10B reaction. D064500100024
However, the reaction 9Be(7Li,alpha)12B may also D064500100025
occur in the primary target, leading to an alpha D064500100026
contamination of the secondary beam. The reaction D064500100027
products are collimated and enter a solenoid that D064500100028
focuses the primary 7Li particles onto a "lollipop" D064500100029
where the 7Li particles are stopped. Because of the D064500100030
different magnetic rigidity, the secondary 6He and D064500100031
alpha particles do not hit the lollipop, but reach D064500100032
the secondary 120Sn target. Typical beam intensities D064500100033
are about 10**4 to 10**5 particles per second at the D064500100034
secondary target position. D064500100035
SAMPLE A 3.8 mg/cm**2 isotopically enriched (98.29%) 120Sn D064500100036
target and a 3.0 mg/cm**2 197Au target have been D064500100037
used as secondary targets. D064500100038
MONITOR (79-AU-197(A,EL)79-AU-197,,DA,,RTH) Because the D064500100039
scattering 4He + 197Au is pure Rutherford at forward D064500100040
angles in the energies of the present experiment, D064500100041
runs with gold targets have been performed just D064500100042
before and after every 120Sn run to normalize the D064500100043
4He + 120Sn cross sections. D064500100044
DETECTOR (TELES,SIBAR,SIBAR) The scattered particles are D064500100045
detected and identified in a system of dE and E D064500100046
silicon detectors. D064500100047
COMMENT The 120Sn(alpha,alpha)120Sn elastic scattering cross D064500100048
section was measured simultaneously with the D064500100049
120Sn(6He,6He)120Sn experiment. D064500100050
