Sažetak
The first experiment in [Lambda]-hypernuclear spectroscopy using the high-precision electron beam at Jefferson laboratory (JLab) has been carried out. The hypernuclear spectrometer system (HNSS) was used to measure spectra from the 12C(e, eK+)12[Lambda]B reaction with sub-1-MeV resolution, the best energy resolution obtained thus far in hypernuclear spectroscopy with magnetic spectrometers. This paper describes the HNSS and the preliminary results for the 12[Lambda]B system. The experimental spectrum is consistent with the expected strong spin-flip excitations of unnatural parity states. A program of hypernuclear physics experiments is planned for the future with much higher yield and even better energy resolution.
