Title: Spectroscopy of A=9 hyperlithium with the $$(e,e^{\prime}K^{+})$$ reaction

Abstract

Missing mass spectroscopy with the $$(e,e^{\prime}K^{+})$$ reaction was performed at JLab Hall C for the neutron rich $$\Lambda$$ hypernucleus $$^{9}_{\Lambda}{\rm Li}$$. The ground state energy was obtained to be $$B_{\Lambda}^{\rm g.s.}=8.84\pm0.17^{\rm stat.}\pm0.15^{\rm sys.}~{\rm MeV}$$ by using shell model calculations of a cross section ratio and an energy separation of the spin doublet states ($$3/2^{+}_1$$ and $$5/2^{+}_1$$). In addition, peaks that are considered to be states of [$$^{8}{\rm Li}(3^{+})\otimes s_{\Lambda}=3/2^{+}_{2}, 1/2^{+}$$] and [$$^{8}{\rm Li}(1^{+})\otimes s_{\Lambda}=5/2^{+}_{2}, 7/2^{+}$$] were observed at $$E_{\Lambda}(\#2)=1.74\pm0.27^{\rm stat.}\pm0.11^{\rm sys.}~{\rm MeV}$$ and $$E_{\Lambda}(\#3)=3.30\pm0.24^{\rm stat.}\pm0.11^{\rm sys.}~{\rm MeV}$$, respectively. The $$E_{\Lambda}(\#3)$$ is larger than shell model predictions by a few hundred keV, and the difference would indicate that a $${\rm ^{5}He}+t$$ structure is more developed for the $$3^{+}$$ state than those for the $$2^{+}$$ and $$1^{+}$$ states in a core nucleus $$^{8}{\rm Li}$$ as a cluster model calculation suggests.
