INTEGRAL and RHESSI spacecrafts recently detected the 1.173 and 1.333 MeV gamma-ray lines coming from the {sup 60}Fe-{sup 60}Co-{sup 60}Ni radioactive decay chain. The long lived isotope {sup 60}Fe (T{sub 1/2} = 1.5 10{sup 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 {sup 59}Fe(n,gamma){sup 60}Fe and {sup 60}Fe(n,gamma){sup 61}Fe cross sections, involved in {sup 60}Fe nucleosynthesis.The direct component of the {sup 60}Fe(n,gamma){sup 61}Fe reaction was studied indirectly via the d({sup 60}Fe,pgamma){sup 61}Fe transfer reaction. The experiment performed in GANIL in spring 2009 will allow to determine the excitation energies of the populated excited states of {sup 61}Fe 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.
