Project Summary


Project Title: Spectroscopy of 13Li
Student Name: Eric Lunderberg
Student's Home Institution: Hope College
Research Advisor: Dr. Paul DeYoung
Source of Support:

This material is based upon work supported by the Howard Hughes Medical Institute and the National Science Foundation under NSF-RUI Grant No. PHY-0969058.

The spectroscopy of neutron-unbound levels in 13Li was examined. The 13Li were formed by a one-proton knockout reaction from a 53.6 MeV/u 14Be beam at the National Superconducting Cyclotron Laboratory. The decay energy spectrum was reconstructed from the four-momenta measured with the Modular Neutron Array (MoNA) and Sweeper superconducting dipole magnet experimental setup. Decays of 13Li, via two-neutron emission, were analyzed using Geant4 simulations. The results will be compared to Yu. Aksyutina et al., Phys. Lett B 666 430 (2008).
