Abstract

The missing-mass spectroscopy of Λ hypernuclei via the (e,eK+) reaction has been developed through experiments at JLab Halls A and C in the last two decades. For the latest experiment, E05-115 in Hall C, we developed a new spectrometer system consisting of the HKS and HES; resulting in the best energy resolution (ΔE≃0.5-MeV FWHM) and BΛ accuracy (ΔBΛ≤0.2MeV) in Λ-hypernuclear reaction spectroscopy. This paper describes the characteristics of the (e,eK+) reaction compared to other reactions and experimental methods. In addition, the experimental apparatus, some of the important analyses such as the semi-automated calibration of absolute energy scale, and the performance achieved in E05-115 are presented.
