Sažetak
Missing mass spectroscopy with the (e, e K+) reaction was performed at Jefferson Laboratory’s Hall C for the neutron-rich hypernucleus 9 Li. The ground-state (g.s.) energy was obtained to be Bg.s. = 8.84 ± 0.17stat. ± 0.15sys. MeV by using shell-model calculations of a cross-section ratio and an energy separation of the spin doublet states (3/21+ and 5/21+). In addition, peaks that are considered to be states of [8Li(3+) ⊗ s = 3/22+, 1/2+] and [8Li(1+ ) ⊗ s = 5/22+, 7/2+] were observed at E (no. 2) = 1.74 ± 0.27stat. ± 0.11sys. and E (no. 3) = 3.30 ± 0.24stat. ± 0.11sys. MeV, respectively. The E (no. 3) is larger than shell-model predictions by a few hundred keV, and the difference would indicate that a 5He + t structure is more developed for the 3+ state than those for the 2+ and 1+ states in a core nucleus 8Li as a cluster model calculation suggests
