Overview of the Hypernuclear Spectroscopy Experiment E01-011 at Jefferson Lab.

Experiment E01-011, ``Spectroscopic Study of $\Lambda $ Hypernuclei up to Medium-Heavy Mass Region Through the (e, e' K$^{+})$ Reaction'', (HKS), was successfully completed during a 2005 summer run in Hall C at the Jefferson Laboratory. Data were taken using C12, Si28, Li6, Li7, and Be9 targets. The experimental geometry included a new High Resolution Kaon Spectrometer (HKS), and implemented a ``Tilt Method'' for the electron spectrometer in order to increase the yield and the signal to accidental ratio. The experiment was designed to achieve a hypernuclear energy resolution of $\sim $400 KeV with rates that match or exceed those obtained using mesonic reactions. These studies will help define the hyperon-nucleon interaction, and the $\Lambda $ effective mass in nuclear media.
