O157100100004 AUTHOR (J.Barrette, E.Deuring, Z.Fraenkel, H.Lehr, I.Tserruya,O157100100005 S.Wald) O157100100006 REFERENCE (J,PR/C,24,2731,1981) O157100100007 INSTITUTE (3ISLWZI) O157100100008 SAMPLE The target consisted of self-supporting Al(2)O(3) with O157100100009 thickness of 350 mug/cm**2, was used. O157100100010 FACILITY (VDGT,3ISLWZI) The 14UD Pelletron accelerator. O157100100011 DETECTOR (TELES,SIBAR,PS) One fragment was detected in a O157100100012 delta-E-E telescope. The delta-E detector was an O157100100013 ionization chamber with a window of 300 mug/cm**2 O157100100014 thickness of Hostaphan. O157100100015 The residual energy was measured with a solid state O157100100016 surface barrier detector of 450-mm**2. O157100100017 The second fragment was detected by a fast, position O157100100018 sensitive detector system, composed of a bi-dimensionalO157100100019 drift chamber and a parallel plate avalanche counter, O157100100020 providing the time signal.The detector had a window of O157100100021 300 mug/cm**2 thickness.The active area of the O157100100022 detector was 30*4 cm**2. The average angle between the O157100100023 small and large detector was 78-degree and it was kept O157100100024 constant in all measurements. O157100100025 METHOD (COINC) coincidence measurement of both O-16 fragments O157100100026 (EDE) O157100100027 COMMENT -By authors.The data were normalized relative to the O157100100028 Faraday cup reading. The absolute normalisation was O157100100029 obtained using the elastic scattering of O-16 on the O157100100030 Al-27 at 29, 45 and 65 MeV. After correcting for the O157100100031 average charge state in the Faraday cup, the O157100100032 normalization constants were consistent within 20% O157100100033 between the three energies. O157100100034 *By authors*.The double differential cross section O157100100035 vs Q is shown in fig.1 for different angles measured. O157100100036 The spectra are similar and show the following featuresO157100100037 -a peak at Q=0 MeV corresponding to the g.s-g.s O157100100038 transition, O157100100039 -a peak at Q approx.-(6-8)MeV corresponding to the O157100100040 excitation of one O-16 fragment into one of the levels O157100100041 of O-16 between 6 and 8 MeV O157100100042 - a peak around Q=-13 MeV corresponding to excitation O157100100043 of both O-fragments to one of the states around O157100100044 E-EXC=6-8 MeV, O157100100045 - a broad tail extending from Q=-16 to -20 MeV is O157100100046 approximately the maximum Q value possible for this O157100100047 reaction and corresponds to a total kinetic energy in O157100100048 the final state close to the Coulomb barrier for two O157100100049 O-16 nuclei.
