The (p,gamma) cross section of Sr-84,Sr-86,Sr-87 isotopes has been measured using activation technique in the proton energy range between 1.5 and 3 MeV. These reactions are relevant to the p-process of stellar nucleosynthesis and in addition, the reaction cross sections in the mass region up to 100 are also important concerning the rp-process associated with explosive hydrogen and helium burning. It is speculated that this rp-process could be responsible for the higher abundances of p-nuclei in this mass region. Natural SrF2 targets were irradiated at the 5 MV Van de Graaff accelerator of the ATOMKI. The induced gamma -activity was measured with a calibrated HPGe detector. The resulting cross sections, important for the quantitative discussion of the production of p-nuclei, are compared with the predictions of statistical model calculations using the NON-SMOKER code.
