D419000100013 METHOD (STTA,ACTIV,GSPEC) D419000100014 Incident energy of the alpha beam: 84.32 MeV, D419000100015 intensity: 3.2 microA. D419000100016 The beam current was determined using monitor D419000100017 excitation functions. D419000100018 The irradiation lasted 240 minutes. D419000100019 Photopeak areas were obtained by adjusting the peak D419000100020 distribution with a gaussian shape plus a straight D419000100021 background. D419000100022 DETECTOR (HPGE) D419000100023 The detector was calibrated in energy and efficiency D419000100024 using a set of radioactive sources with well-known D419000100025 activities: 22Na, 57Co, 60Co, 133Ba, 137Cs, 152Eu.

D419000100036 ERR-ANALYS (ERR-T) The uncertainties in the cross sections arise D419000100037 essentially from the errors in the peak areas and the D419000100038 efficiency calibration. D419000100039 (ERR-S,5.,8.) The contribution of the first factor D419000100040 depends on the peak area and the background, and was D419000100041 estimated to be around 5% to 8%. D419000100042 (ERR-1) The second contributes with 5%. D419000100043 Therefore, the data are affected by an overall error D419000100044 of 15%. D419000100045 ADD-RES (THEO) The experimental data were compared with the D419000100046 independently interacting excitons, the Index model, D419000100047 which can explain both the equilibrium and D419000100048 pre-equilibrium effects.
