Topic: Prospects for future studies of neutron-unbound systems and correlations in multi-neutron decays around the dripline

The Neutron-Unbound Systems Around the Dripline workshop is a scientific program for multi-neutron decays hosted by the Facility for Rare Isotope Beams / National Superconducting Cyclotron Laboratory (FRIB/NSCL) at Michigan State University (MSU).

Studies of near-dripline, neutron-unbound systems (ND-NUS) provide important insights that help develop our descriptions of atomic nuclei. This workshop will provide opportunities to review recent investigations and discuss future work in this exciting field.

Session Topics

  • Nuclear structure and the continuum
  • Measurements and interpretations of 2n emission
  • The tetraneutron and many-body decays
  • Advances in detector systems

Topics for discussion

  • Recent measurements and state of the art techniques for measuring ND-NUS. What challenges will be involved with future measurements?
  • Ideas for improving detectors, analysis methods, etc.
  • State of the art theoretical models and tools for interpreting measurements of ND-NUS. What challenges are involved in modeling these systems and how can future measurements provide input?
  • Continued discussions of n-n correlations extended to the context of four- and higher-body decays of these systems
  • Possible collaborations (theory + experiment) for studying ND-NUS

Recent technical developments from collaborations that undertake invariant mass spectroscopy of neutron unbound systems, e.g. SAMURAI, R3B, and MoNA, combined with increasingly high intensity exotic beams, have opened the road toward improved measurements of nuclei near and beyond the neutron dripline. Such capability will allow for detailed spectroscopic studies of neutron-unbound systems and the mechanisms by which they decay. In particular, experimental investigations of multi-neutron correlations may shed light on the role of multi-nucleon interactions and resonant and non-resonant particle continuum in the structure of extremely neutron-rich nuclei which can aid in the development of nuclear interaction models. This workshop will provide opportunities to continue discussions from the Nuclear Physics at the Edge of Stability (NPES) workshop (June 28 - July 1, 2021). We highly recommend participation in NPES. Following this, we would like to welcome the entire community to discuss recent results and future developments specific to systems near the neutron-dripline, from both the experimental and theoretical perspectives.
