Abstract:

The ground state structure of [superscript 9]Li has been investigated through the d([superscript 9]Li, t)[superscript 8]Li one-neutron transfer reaction at E/A = 1.68 MeV. The [superscript 8]Li sub-system in [superscript 9]Li was observed in its lowest three energy levels. The spectroscopic factors derived from a DWBA analysis are fairly consistent in trend with model calculations. The understanding of the N = 6 sub-shell closure from the spectroscopic information and neutron separation energies is discussed.
