摘要：

Measuring the resonance strengths of the Mg-25(p,gamma)Al-26 reaction at energies of astrophysical interest poses a very difficult task for the usual prompt gamma-ray detection method. Here we describe an alternative method in which targets are first irradiated and the produced Al-26 nuclei are off-line counted by means of AMS. An overall efficiency of 4 x 10(-5) could be achieved extracting AlO- from the ion source. For this purpose, a careful chemical treatment of the samples and the use of a gas filled magnet were necessary. (C) 2004 Elsevier B.V. All rights reserved.
