Hypernuclear Project with HRS-HKS
Experiments
Approved
- E12-15-008 (40, 48ΛK)
- E12-20-013 (208ΛTl)
Conditionally Approved
- C12-19-002 (3, 4ΛH)
- C12-20-003 (3Λn)
Overview
The experiment is planned to be done with high resolution spectrometers HRS and HKS in JLab Hall A for high precision hypernuclear measurement. Electron beams at 4.24 GeV will be impinged on various targets (3, 4H, 40, 48Ca, 208Pb), and scattered electrons and K+s from the (e,e'K+) reaction will be detected by the spectrometers for missing mass spectroscopy.
