The primary Li-7(3+) beam was O236400100022 provided by LNL-XTU tandem with energies of 31 and 33 O236400100023 MeV. The primary beam was directed on the a 5 cm long O236400100024 hydrogen gas cell, which had 5 um thick Havar foil O236400100025 windows. The effective thickness of the gas cell was O236400100026 2 mg/cm**2. For production of the 13 MeV Be-7 beam, an O236400100027 energy degrader was used. O236400100028 DETECTOR (PPAC) Before entering the target chamber, the beam O236400100029 passes through 2 PPAC detectors. O236400100030 (SISD,TELES) Reaction products were detected by six O236400100031 telescope detectors positioned around the target. O236400100032 Each detector consisted of a 55 um and a 300 um thick O236400100033 double-sided silicon strip detector with active areas O236400100034 of 64*64 mm**2 O236400100035 METHOD (EXTB,EDE,SITA) The production of He-3 and He-4 O236400100036 particles was studied in the Be-7 + Si-28 reaction at O236400100037 three near barrier energies, namely at 13, 20 and 22 O236400100038 MeV. Angular distributions and production cross O236400100039 sections were obtained.
