Spectroscopy of electroproduced light to medium mass lambda hypernuclei

Abstract

The E01-011 experiment at Jefferson Laboratory (JLab) studied light-to-medium mass Λ Until recently, hypernuclei were studied at accelerator facilities with intense π + and K -meson beams. The poor quality of these beams limited the resolution of the hypernuclear excitation energy spectra to about 1.5 MeV (FWHM). This resolution is not sufficient for resolving the rich structure observed in the excitation spectra. By using a high quality electron beam and employing a new high resolution spectrometer system, this study aims to improve the resolution to a few hundred keV with an absolute precision of about 100 keV for excitation energies. hypernuclei via the ( 1)AIn this work the high-resolution excitation spectra of In conclusion, the discrepancies found in this study will provide valuable input for the further development of theoretical models.v
