D047600100012 84 mu-g/cm2, evaporated onto a 15 microg/cm2 C backing.D047600100013 For the ER measurements, a target backed by an Al D047600100014 catcher foil was used; the Al foil was 550 mu-g/cm2 D047600100015 in thickness, so as to stop the recoiling heavy D047600100016 residues well within the foil. The reaction products D047600100017 were identified by their distinctive alfa-energies D047600100018 and half-lives (182 ns to 23.9 min). D047600100019 DETECTOR (MWPC,PS,SIBAR) For normalization, two monitor D047600100020 detectors, placed at angles of 22.5 degrees above D047600100021 and below the beam axis, measured the elastically D047600100022 scattered beam particles. Fission fragments D047600100023 following fusion were detected in the CUBE detector D047600100024 array, using a large area (357 mm x 284 mm) position D047600100025 sensitive multiwire proportional counter covering D047600100026 laboratory angles from 95-170 degrees. However, the D047600100027 measurements were restricted to the angular range D047600100028 95-165 degrees, since an annular silicon surface D047600100029 barrier detector was placed 8 cm from the target, at D047600100030 a mean angle of 174 degrees, to detect the decay D047600100031 alfa-particles from the evaporation residues.
