Feasibility Tool for Neutron Capture on Radioactive Isotopes — •Muaz Al Halabi — Goethe Universität, Frankfurt am Main, Germany
The slow neutron capture process (s-process) is particularly significant for understanding the production of elements heavier than iron across different astronomical environments. Neutron capture measurements can be used to study the s-process using the activation technique. Three key parameters define such an experiment: a sufficient neutron flux (φn), a target isotope for activation, and a detector to identify the newly produced product isotope through a direct neutron capture (n,γ) measurement.
It is particularly challenging, however, when both the target and product isotopes are radioactive. In such cases, emissions from the target can create a background that interferes with detecting emissions from the product isotope, making it difficult to identify the product. Therefore, accurately determining the required neutron flux for activation experiments is essential to ensure that detectors can distinguish the product isotope’s emissions from those of the target.
This presentation introduces a simulation-based method to help experimentalists quickly estimate the required neutron flux for activation experiments and evaluate their feasibility.
