Title: Spectroscopic Investigation of Λ Hypernuclei by the (e,e′K+) Reaction

Speaker: 陈春花博士(Hampton University)

Abstract:

Hypernuclear spectroscopy is a powerful tool to investigate ΛN interaction. Compared with other Λ hypernuclei productions, electroproduction via the (e,e′K+) reaction has the advantage of exciting states deeply inside of the hypernucleus and achieving sub-MeV energy resolution. The experiment E05-115, which was successfully performed in 2009, is the third generation hypernuclear experiment in JLab Hall C. The analysis of the experiment provides the clearest level structure to the date of this hypernucleus produced by the (e, e′K+) reaction. This talk will give the introduction of the Λ hypernuclei, the experiment of E05-115, and discuss the results on the spectra of 12ΛB,7ΛHe, and 10ΛBe.
