Indirect Study of Neutron Capture for 63Fe(n,g)
ORAL
Abstract
Far from stability, little is known about neutron capture. An indirect method known as the $\beta$Oslo method allows n-capture rates to be experimentally constrained for radioactive nuclei. The reaction product is populated in $\beta$decay, and the $\gamma$ strength functions ($\gamma$SFs) and nuclear level densities (NLDs) are extracted simultaneously. These are used to constrain the n-capture rate. In the FeCd region, an unexpected low-energy enhancement (LEE) in the $\gamma$-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.
