摘要：

INTEGRAL and RHESSI spacecrafts recently detected the 1.173 and 1.333 MeV gamma-ray lines coming from the Fe-60 - Co-60 - Ni-60 radioactive decay chain. The long lived isotope Fe-60 (T-1/2 = 1.5 10(6)y) is believed to be primarily produced in core-collapse supernovae. However the interpretation of the observations is difficult because of the large uncertainties concerning Fe-59(n,gamma)Fe-60 and Fe-60(n,gamma)Fe-61 cross sections, involved in Fe-60 nucleosynthesis. The direct component of the Fe-60(n,gamma)Fe-61 reaction was studied indirectly via the d(Fe-60,p gamma)Fe-61 transfer reaction. The experiment performed in GANIL in spring 2009 will allow to determine the excitation energies of the populated excited states of Fe-61 and for the first time their spectroscopic factors as well as their transfer angular momentum. I will first give an overview of the astrophysical context, then I will describe the experimental setup and finally present some preliminary results of the ongoing analysis.
