Electroproduction of kaons on light nuclei
The A(e,e'Κ+)YX reaction on H, D, 3He, and 4He was investigated in Hall C at CE-BAF. Data were obtained for Q2 ≈ 0.35 and 0.5 GeV2 at 3.245 GeV. The missing mass spectra for both H and D are fitted with Monte-Carlo simulations incorporating peaks corresponding to Λ production on the proton and Σ production on both the proton and neutron. For D, the cross section ratio Σ0/Σ- ≈ 2, and excess yield close to the thresholds for Λ and Σ production can be attributed to final-state interactions; models are compared to the data. The analysis of the data for the He targets is in a more preliminary state with broader quasi-free peaks resulting from the higher Fermi momenta. Evidence for bound Λ-hypernuclear states is seen and other structure may be present.
