Thin-window gas cell target for activation cross-section measurements relevant for nuclear astrophysics

Abstract A thin-window gas target system was designed in order to fulfill the requirements of the measurement of low energy α - induced reaction cross-sections relevant for nuclear astrophysics using the activation method. The properties of the gas cell system, its characterization and the results of the first feasibility studies on the He 3 ( α , γ ) Be 7 and Xe 124 ( α , γ ) Ba 128 reactions are summarized.
