摘要

The experiment was performed at the National Laboratory of Heavy Ion Research of the Institute of Modern Physics,Lanzhou,China.The secondary beams of radioactive isotopes were produced by the fragmentation of the 12C6+primary on a 9Be target with a thickness of 2 652 m[1;2].The secondary beams,7Be,8B and 9C beams were delivered by the Radioactive Ion Beam Line in Lanzhou(RIBLL)[3,4]and impinged on a natPb target at RIBLL Terminal.The energies of the secondary beams,at the physical target,were about three times the Coulomb barriers,130 MeV for 7Be,178 MeV for 8B and 227 MeV for 9C,respectively.
