The measurements of elastic scattering angular distribution of 17F and 17O on 208Pb target around 7 MeV/u have been performed at RIBLL. The primary beam of 70 MeV/u 20Ne from SSC bombarded on the primary target (Be, 3.5 mm in thickness), which was installed in the TO chamber of RIBLL. The secondary beams of 17F or 17O were selected with D1, D2 and the degrader located at C1, and degraded the energies at T1 with the Al foils. The secondary beams with proper energies were then transported to T2 and hit on the 208Pb target (with thickness of 2 mg/cm2) there. The detector arrangement is schematically shown in Fig.1.
