Absolute cross sections of the Sr-86(alpha,n)Zr-89 reaction at energies of astrophysical interest

Absolute cross sections for the Sr-86(alpha,n)Zr-89 reaction at energies close to the Gamow window are reported. Three thin SrF2 targets were irradiated using the 9MV Tandem facility in IFIN-HH Bucharest that delivered a beams for the activation process. Two high-purity Germanium detectors were used to measure the induced activity of Zr-89 in a low background environment. The experimental results are in very good agreement with Hauser-Feshbach statistical model calculations performed with the TALYS code.
