2 Astrophysical Motivation 496. Wilhelm und Else Heraeus-Seminar Tanja HeftrichFebruary 07th, 2012 INTEGRAL measured 60 Fe/ 26 Al ratio along the galactic plane deep-sea manganese crust 60 Fe 60 Fe is an important s-process isotope determine production and destruction rates R. Diehl Knie et al, PRL 93 (2004)

3 496. Wilhelm und Else Heraeus-Seminar Tanja HeftrichFebruary 07th, Fe 60 Fe(n, ) 61 Fe : activation kT = 25 meV 59 Fe(n, ) : extremely difficult 60 Fe( - ) : in progress, new measurements: 1.49 Myr / 2.62 Myr 60 Fe(,n) : coulomb dissociation 60 Fe(n, ) 61 Fe : activation kT = 25 keV 60 Fe(n, ) 61 Fe : kT = 90 keV

4 60 Fe(n, ) 61 TRIGA 60 Fe sample was produced at the PSI in Villigen, Switzerland (ERAWAST I workshop) irradiation with thermal neutrons to get the depletion of 60 Fe at kT = 25meV 496. Wilhelm und Else Heraeus-Seminar Tanja HeftrichFebruary 07th, 2012
