【 摘 要 】

In this paper we present the ongoing experiments at ATOMKI related to our systematic γ-process studies. These studies are intended to enlarge the limited experimental database from α-induced reactions on nuclei in the heavier mass range of the γ -process. In all presented cases the activation method was used. The details of the cross section measurements and preliminary results on115In(α,n)118mSb,115In(α,γ)119Sb;162Er(α,n)165Yb,162Er(α,γ)166Yb,164Er(α,n)167Yb,166Er(α,n)169Yb;191Ir(α,n)194Au,191Ir(α,γ)195Au,193Ir(α,n)196mAu,193Ir(α,n)196Au reactions are presented.
