Investigation of the reaction mechanism in the neutron emission from unbound excited states in ²⁷F by the MoNA Collaboration

The MoNA Collaboration has been conducting experiments over the past two decades at the National Superconducting Cyclotron Laboratory (NSCL) and is poised to expand its scientific program with the upcoming Facility for Rare Isotope Beams (FRIB), both located in East Lansing, MI. The Collaboration primarily focuses on the study of unbound nuclei along the neutron dripline using invariant mass spectroscopy. A recent analysis of data on the production of ^25,26O from ²⁷F and ²⁹Ne beams incident on beryllium targets indicates a possible new and rich program to investigate the production mechanism of these neutron rich nuclei. We have extended this work to study the neutron emission from unbound excited states in ²⁷F (²⁷F → ²⁶F + n) populated via  ²⁸Ne(-1p) and ²⁹Ne(-2p) proton removal reactions. This presentation will discuss preliminary results from this study.
