Accelerator mass spectrometry (AMS) represents a complementary approach for precise measurements of neutron capture cross sections, e.g., for nuclear astrophysics. This technique, completely independent of previous experimental methods, was applied for the measurement of the 54Fe(n,γ) 55Fe reaction. Following a series of irradiations with neutrons from cold and thermal to keV energies, the produced long-lived 55Fe nuclei (t1/2=2.744+−0.009) yr) were analyzed at the Vienna Environmental Research...[Show more]
