CommentsBeam quality: no data Target: The target consists of a self-supported foil of 208Pb with a thickness of 1mg/cmm2. Its isotopic composition was the following: 208Pb 98,43%, 207Pb 1,05%, 206Pb 0,51%, 204Pb 0.01%. Data obtained: author graph (digitized with GSYS 2.4 ) The experiment was performed in the G21 line at the SPIRAL-GANIL facility, where high quality beams of 8He are produced from the fragmentation of a 13C beam at 75 MeV/nucleon on a dedicated target for the production of helium isotopes. The detection system, GLORIA (GLObal RactIon Array), was recently developed at the University of Huelva for studing the structure and dinamics of exotic nuclei.
