O157400100004 AUTHOR (R.Lichtenthaler, A.Lepine-Szily, A.C.C.Villari, O157400100005 W.Mittig, V.J.G.Porto, C.V.Acquadro) O157400100006 INSTITUTE (3BZLUSP) O157400100007 REFERENCE (J,PR/C,26,2487,1982) O157400100008 FACILITY (VDGT,3BZLUSP) Pelletron Laboratory of the University O157400100009 of Sao Paulo O157400100010 SAMPLE An isotopically enriched Mg-24 target, evaporated in O157400100011 C-12 backing, were used. O157400100012 For normalization purposes, a 1 mug/cm**2 thick gold O157400100013 layer was evaporated on the targets. O157400100014 DETECTOR (TELES,PROPC,SIBAR) Three sets of delta-E-E telescopes O157400100015 were used, the E detector was standard Si surface O157400100016 barrier detectors, the delta-E detectors proportional O157400100017 counters for the forward angles and surface barrier O157400100018 detectors for the backward angle data. O157400100019 A monitor detector placed at 15-degree with respect O157400100020 to the beam permitted to calculated the ratio of Mg-24 O157400100021 to gold target thicknesses. O157400100022 COMMENT *By authors*.The absolute cross sections were obtained O157400100023 by normalizing to Rutherford scattering on gold and O157400100024 using the ratio of target thicknesses. The energy O157400100025 resolution at all angles was sufficient to separate O157400100026 the elastic peal from inelastic peaks. O157400100027 ADD-RES (COMP).Optical model and closed-formalism parameters. O157400100028 A typical proton spectrum of C-12 ions elastically O157400100029 scattered at Ang(lab)=40 degree and spectra of O-16 O157400100030 originating from the Mg-24(6-C-12,O-16)Ne-20(g.s) O157400100031 transfer reaction were obtained. O157400100032 ERR-ANALYS The absolute errors in the elastic cross section are 5%O157400100033 for the forward angles and 10-20% for intermediate O157400100034 angles. O157400100035 (DATA-ERR).The error is reported by authors on fig. O157400100036 (ANG-ERR-D).Digitizing error of angle. O157400100037 STATUS (CURVE) By CAJAD.
