C296800100017 INC-SPECT Primary beams of 6Li(3+) at 23.8, 24.8, 26.1, 29, and C296800100018 30 MeV were produced by the Notre Dame FN tandem C296800100019 accelerator and impinged on a primary 2.5-cm-long C296800100020 gaseous primary target containing 850 Torr of 2H. The C296800100021 intensity of the primary beams was 300 to 500 enA, C296800100022 producing secondary 7Be beams via the direct reaction C296800100023 6Li(2H,n)7Be at intensities ~5*10**5 pps. The C296800100024 produced secondary beams were collected and C296800100025 transported via the TriSol solenoid system to a C296800100026 1.95-mg/cm2-thick natZr secondary target with C296800100027 energies of 20.6, 22.1, 23.7, 27.3, and 28.2 MeV. C296800100028 Another possible explanation for the discrepancy C296800100029 could be the uncertainty in the beam energy, which C296800100030 was estimated to be of the order of +-0.5 MeV. C296800100031 DETECTOR (SISD,TELES) The quasielastic scattered nuclei, C296800100032 including the excitation to the first excited state C296800100033 of 7Be, together with other reaction products were C296800100034 detected by four silicon telescopes. The DSSSD C296800100035 detectors with dimensions of 5.4x5.4cm provide 16 C296800100036 strips distributed horizontally and 16 strips C296800100037 vertically, allowing a pixel by pixel analysis and an C296800100038 interstrip rejection. C296800100039 SAMPLE A natZr target of 1.95 mg/cm2 thickness. C296800100040 METHOD (EDE) The telescopes produced an excellent C296800100041 discrimination between the 7Be recoils and the C296800100042 various reaction products by energy via the dE-E C296800100043 technique. With appropriate gates on such spectra and C296800100044 after interstrip rejection, yields of the elastic C296800100045 scattered 7Be nuclei at various angles corresponding C296800100046 to the 16 vertical strips of each telescope were C296800100047 integrated and normalized to the target scattering C296800100048 centers, to the geometrical solid angle, and to the C296800100049 flux. The flux was adjusted at the most forward C296800100050 angles, such as the elastic scattering versus C296800100051 Rutherford, to be unity and differential cross C296800100052 sections were obtained. C296800100053 ERR-ANALYS (DATA-ERR) The assigned errors to the total reaction C296800100054 cross sections correspond to angular distributions.
