The present paper describes preparation and characterization of strontium targets for nuclear astrophysical experiments with alpha particles accelerated near the Gamow window energy. SrF 2 and SrCO 3 targets were obtained by thermal evaporation in similar conditions. Target characteristics (thickness, chemical purity and surface morphology) were determined via α transmission measurements, XRD and SEM/EDX analysis. The results reveal the SrF 2 target exhibits better properties compared to the SrCO 3 one for our nuclear astrophysics experiments. This result was supported by nuclear activation measurements with an α beam at the Bucharest Tandem 9 MV accelerator.
