The 25Mg(n,gamma) reaction cross-section has been measured at the neutron time-of-flight facility n TOF at CERN in 2003 and, with an improved experimental set up, in 2012. These measurements aim at addressing important astrophysical issues related to the s process. Highly-enriched 25Mg samples have been used, in the form of MgO powder and Mg metal sample. Preliminary results from the 2012 measurement and comparisons with previous data are shown.
