Reaction production + AMS: An alternative method to study low energy reactions. 26Al as a test case

Considering the importance of the 26 Al nuclei in Astrophysics, in this work, preliminary results regarding a campaign of measurements related with this radioisotope production, are presented. We have taken advantage of two different facilities: first, the radio-nucleus is produced by means of irradiation of targets selected in correlation with particular reactions; once the enrichment with 26 Al was made, the targets are analyzed in an AMS machine to obtain the concentration of 26 Al produced during the irradiation. With this off-line method, it is possible to measure acceptable small cross sections of a selected low energy reaction. In this work, our preliminary results for three different energies of 28 Si(d,α) 26 Al reaction cross sections are shown, as well as our first considerations to commence with measurements of 25 Mg(p,γ) 26 Al reaction cross sections below 1 MeV.
