Abstract: MC.00009 : Projectile-like fragment production studies using coincident neutrons*
4:00 PM–4:15 PM
the MoNA Collaboration
The production of nuclei near the neutron dripline at Radioactive Ion Beam (RIB) facilities requires multi-step reactions between primary beams and targets. Understanding these multi-step reactions narrows constraints on secondary beam production rates and therefore optimizes beam time. Experimental planning typically depends on empirical parameterizations like EPAX, but results can differ from experiment . At the National Superconducting Cyclotron Laboratory (NSCL), the MoNA Collaboration measured coincident neutrons and charged fragments in the 32Mg + 9Be reaction in order to study the formation of the precursor states, i.e. projectile-like fragments (PLF’s). Charged fragments were deflected by the Sweeper magnet into a suite of charged particle and coincidence neutrons measured in the Modular Neutron Array (MoNA). The rigidity of the Sweeper was varied during this experiment allowing the detection of a range of isotopes. Analysis of the neutron multiplicity and energy distributions in coincidence with sodium, neon, or fluorine charged fragments will be presented.
