O160700100011 SAMPLE A 94-mug/cm**2 Sm-144 target, enriched to 88.6% and O160700100012 supported on a 30-mug/cm**2 carbon backing, was used. O160700100013 ADD-RES (COMP).The framework of the optical model. O160700100014 FACILITY (VDGT,3ARGCNE) The 20-UD tandem accelerator at the O160700100015 tandar-laboratory in Buenos Aires. O160700100016 DETECTOR (SIBAR) A five 150-mum surface barrier silicon countersO160700100017 with energy resolution approx 700-800-KeV. A monitor O160700100018 detector was placed at 20-degree for normalization. O160700100019 METHOD (SITA) O160700100020 COMMENT *By authors*.For angles smaller than ang-cm=110-degree O160700100021 the elastic and inelastic peaks were not resolved. O160700100022 Therefore, in this angular range the differential crossO160700100023 sections for the elastic scattering include a small O160700100024 contribution less than 5% due to the inelastic channel.O160700100025 ERR-ANALYS The main contributions to uncertainties in the O160700100026 evaluation of the cross sections arise from- O160700100027 the unfolding procedure of the elastic and inelastic O160700100028 peaks, background subtraction and statistical errors O160700100029 (the error bars of the figures take into account all O160700100030 these factors). O160700100031 Systematic errors arising from uncertainties in the O160700100032 position of the monitor, in the evaluation of solid O160700100033 angles and in the contribution of target contaminants O160700100034 to the peaks of interest. O160700100035 (ERR-1).The error in target contaminants is 2%. O160700100036 STATUS (CURVE).By CAJAD.
