Abstract : Al-26 was the first cosmic radioactivity ever detected in the galaxy as well as one of the first extinct radioactivity observed in refractory phases of meteorites. Its nucleosynthesis in massive stars is still uncertain mainly due to the lack of nuclear information concerning the Al-26(n,p)Mg-26 and Al-26(n,alpha)Na-23 reactions. We report on a single and coincidence measurement of the Al-27(p,p')Al-27(p)Mg-26 and Al-27(p,p')(27) Al(alpha)Na-23 reactions performed at the Orsay TANDEM facility aiming at the spectroscopy study of Al-27 above the neutron threshold. Fourteen states are observed for the first time within 350 keV above the Al-26+n threshold.
