The thickness of natural C212900100015 samples varied between 1.36 and 5.60 mg/cm2. C212900100016 Thickness of enriched 58Ni samples varied between C212900100017 0.725 and 0.924 mg/cm2. C212900100018 DETECTOR (TELES,SIBAR,SIBAR) Several dE-E silicon surface- C212900100019 barrier telescopes were used at backward angles to C212900100020 detect protons evaporated from the fused system. C212900100021 Either three telescopes at 120,135 and 150 deg or C212900100022 four telescopes at 112.5, 127.5,142.5 and 157.5 deg C212900100023 were used in various experimental runs. C212900100024 METHOD (EDE,TOF) C212900100025 INC-SOURCE 7Be isotope was generated by means of the one proton C212900100026 transfer reaction 3He (6Li,7Be). Mixed secondary beam C212900100027 consisting of 8B, 7Be, and 6Li with rates of C212900100028 0.5-1.2E+5 particles/s were produced using primary C212900100029 6Li3+ beams with energies between 31 and 38 MeV.
