Indirect Study of Neutron Capture for 63Fe(n,g)
Abstract
Far from stability, little is known about neutron capture. An indirect method known as the β-Oslo method allows n-capture rates to be experimentally constrained for radioactive nuclei. The reaction product is populated in β-decay, and the γ strength functions (γSFs) and nuclear level densities (NLDs) are extracted simultaneously. These are used to constrain the n-capture rate. In the Fe-Cd region, an unexpected low-energy enhancement (LEE) in the γ-decay probability has been observed. The presence of this can have a significant influence on neutron capture rates. The LEE is expected in the neutron-rich Fe isotopes. At the NSCL, 64Fe was measured with the Summing NaI detector. Recent results will be presented with a focus on the presence of the LEE.
