First observation of the ¹³Li ground state

NUCLEAR REACTIONS ⁹Be(¹⁴Be, ¹³Li), [¹⁴Be secondary beam from ⁹Be(¹⁸O, X), E=120 MeV/nucleon primary beam], E=53.6 MeV/nucleon; measured ¹¹Li fragment and neutron spectra, three-body (¹¹Li+n+n), and two-body (¹¹Li+n) decay energy spectra using Modular Neutron Array (MONA) for neutrons at NSCL facility. Monte Carlo and GEANT4 simulations. Glauber reaction model. ^12,13Li; deduced levels, ground state resonance energies. Strong dineutron character for ¹³Li g.s. Comparison with previous studies.
