The thickness of the D432800100019 targets varied between 0.410 mg/cm2 and 1.042 D432800100020 mg/cm2, determined by weight measurement. D432800100021 DETECTOR (HPGE) D432800100022 METHOD (ACTIV,GSPEC,EDEG,SITA,EXTB) The reaction cross D432800100023 sections of 107Ag(a,g)111In and 107Ag(a,n)110In were D432800100024 determined in energy ranges Ecm=7.79-12.50MeV and D432800100025 Ecm=8.57-12.50MeV respectively by using activation D432800100026 technique. Some beam energies could not be produced D432800100027 by the cyclotron, therefore, aluminum and nickel D432800100028 energy degrader foils were used. During the D432800100029 irradiation the target stability was monitored by an D432800100030 ion-implanted Si detector, placed at 165deg relative D432800100031 to the beam direction. Typical beam current was D432800100032 150-800nA. After each irradiation the target was D432800100033 transported to a low-background counting setup. The D432800100034 activity of targets was measured with a HPGE detector D432800100035 equipped with 4pi, 10 cm thick lead shielding. D432800100036 ERR-ANALYS (EN-ERR) includes the uncertainty of the primary beam D432800100037 energy (0.5%), the energy loss in target (0.6-1.0%) D432800100038 and thickness of the degrader foils (1%) D432800100039 (ERR-T) The uncertainty of the cross section is D432800100040 calculated as the quadratic sums of the following D432800100041 errors: D432800100042 (ERR-1) gamma-detection efficiency (7%) D432800100043 (ERR-2) target thickness (7%) D432800100044 (ERR-3,,3.1) decay parameters (<=3.1%) D432800100045 (ERR-S,0.6,14.0) counting statistics (0.6-14.0%) D432800100046 ADD-RES (THEO) The resulting experimental cross sections were D432800100047 compared to theoretical Hauser-Feshbach model D432800100048 calculations with the code SMARAGD. D432800100049 (POT) An alpha + nucleus optical potential with an D432800100050 energy dependent alpha width was proposed to fit the D432800100051 experimental data.
