Investigation of Alpha-Induced Reactions on ¹⁰⁷Ag at Astrophysical Energies

Cross sections of the ¹⁰⁷Ag(α, γ)¹¹¹In and ¹⁰⁷Ag(α,n)¹¹⁰In reactions have been measured with the activation method at effective center-of-mass energies between 7.79 MeV and 12.00 MeV close to the astrophysical energy range. The irradiation and counting of the ¹⁰⁷Ag targets was carried out at ATOMKI using the cyclotron accelerator and the low background counting facility, respectively. Cross section results are presented and compared with the predictions of Hauser-Feshbach statistical model calculations using the NON-SMOKER and TALYS-1.4 codes. In general, above 10 MeV, the model calculation are able to reproduce reasonably well the experimental data, but below 10 MeV, depending on some input parameters strong deviations are also found.
