Abstract

Considering the importance of the ²⁶Al 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 ²⁶Al was made, the targets are analyzed in an AMS machine to obtain the concentration of ²⁶Al 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 ²⁸Si(d,α)²⁶Al reaction cross sections are shown, as well as our first considerations to commence with measurements of ²⁵Mg(p,γ)²⁶Al reaction cross sections below 1 MeV.
