摘要: The first measurements of the capture reactions for astrophysical γ-process using HECTOR, a total absorption spectrometer are presented. Two reactions: 102Pd(p,γ)103Ag and 90Zr(α,γ)94Mo were measured γ-summing technique. results compared with previous found in literature NON-SMOKER predictions. from current work good agreement data serve as test newly developed detector.
