A025200100014 FACILITY (CYCLO,2BLGLVN) A025200100015 SAMPLE 275 mu-gr/cm2 polyethylene target. A025200100016 DETECTOR (SIBAR) Protons from the elastic scattering and A025200100017 alpha-particles from the (p,alpha) reaction were A025200100018 detected in the Louvain-Edinburgh detector array (LEDA)A025200100019 a concentric multistrip silicon detector that provided A025200100020 data at sixteen angles from 12 to 28 degrees in the A025200100021 lab. System with a very large coverage (90%) in the A025200100022 azimuthal angle. A025200100023 METHOD (SITA) A025200100024 (EDEG) the 14 MeV 18-F beam was first degraded to 10 A025200100025 MeV in a 300 mu-gr/cm2 carbon foil in front of a 275 A025200100026 mu-gr/cm2 polyethylene target in which it was slowed A025200100027 down to 5.0 MeV; the C.M. energy region from 265 to A025200100028 535 keV was scanned.

A025200200005 ANALYSIS (INTAD,SLA) A025200200006 COMMENT - by authors: as the angular region covered by the A025200200007 detector at the resonance energy was from 20 to 40 A025200200008 C.-M. degrees, the corrected number of counts was then A025200200009 extrapolated to 4*pi solid angle, using the l=1 A025200200010 character of the angular distribution.
