The method of sequential neutron decay spectroscopy beginning with a primary beam of 60 MeV/nucleon ⁴⁸Ca was investigated as a potential tool to measure unbound resonances in neutron-rich nuclei. Neutrons were measured in coincidence with fragments, and unbound resonances were observed for ¹⁰Li, ^12,13Be, and ²³O. The method is currently limited to resonances with small decay energies (coration:none; color:black"" href=""/science?_ob=MathURL&_method=retrieve&_udi=B6TVB-4RKTN8M-2&_mathId=mml1&_user=1067359&_cdi=5530&_rdoc=3&_acct=C000050221&_version=1&_userid=10&md5=55ae59453c13403e3d3b6d570357b835"" title=""Click to view the MathML source"" alt=""Click to view the MathML source"">E_decayc=""http://www.sciencedirect.com/scidirimg/entities/2272.gif"" alt=""less, approximate"" title=""less, approximate"" border=""0"">100 keV) in lighter (coration:none; color:black"" href=""/science?_ob=MathURL&_method=retrieve&_udi=B6TVB-4RKTN8M-2&_mathId=mml2&_user=1067359&_cdi=5530&_rdoc=3&_acct=C000050221&_version=1&_userid=10&md5=e1bfd59bfa9164f0ff3a380ac8d80f82"" title=""Click to view the MathML source"" alt=""Click to view the MathML source"">Zc=""http://www.sciencedirect.com/scidirimg/entities/2a7d.gif"" alt=""less-than-or-equals, slant"" title=""less-than-or-equals, slant"" border=""0"">10) nuclei, and the possibility of extending it to heavier, more neutron-rich nuclei will be discussed.
