C221400100016 DETECTOR (SISD) The TECSA array made up of 8 YY1-300 Micron C221400100017 detectors (each one with 16 arch strips), was set at C221400100018 190mm from target covering angles in the range C221400100019 15-40 deg was optimized for the alpha particle C221400100020 detection. C221400100021 (SISD) 15O ions were detected using two position C221400100022 sensitive detectors (PSD, type X1,16 strips each), C221400100023 placed symmetrically at 340mm and covering angles C221400100024 from 15O = 3deg - 12. deg. C221400100025 INC-SOURCE 18F beam was produced via the p(18O,18F)n reaction, C221400100026 after energy degrading of the primary beam by means C221400100027 of an Al degrader (around 30 mu-m thick).After C221400100028 isotopic selection the obtained secondary beam was C221400100029 tuned through MARS with a final energy of 52MeV on a C221400100030 position sensitive detector at the target location of C221400100031 TECSA C221400100032 ANALYSIS (TROJA) In adopted Trojan Horse Method the method is C221400100033 based on the quasifree deuteron breakup, where C221400100034 deuteron breaks up into participant particle p and C221400100035 spectator particle n. Here the 18F(d,alpha n) 15-O C221400100036 measurement was performed to obtain information on C221400100037 18F(p,alpha) 15-O cross section at energies relevant C221400100038 for astrophysics. FRom measured cross sections reactionC221400100039 rarts for 18F(p,alpha)15-O was determined C221400100040 METHOD (COINC) Coincidence between alpha particles and 15-O C221400100041 ions was required. Neutrons were undetected and their C221400100042 momentum distribution was inferred from C221400100043 HISTORY (20210821C) Compiled by S.H.
