Comments
Beam quality: The purity of 6He was 48%. The intensity of the secondary beam was about 2000 pps.
Target: The 9Be target was 200 mcm thickness and 900 mm2 effective area.
Data obtained: author graph (digitized with GSYS 2.4)
The quasi-elastic scattering was mesuared. The experiment was performed with radioactive ion beam line that was built up at Heavy Ion Research Facility in Lanzhou. The secondary beam of 6He was produced by fragmentation of a 50 MeV/u 13C primary beam on a 3000 mcm thick 9Be production target.
