We report measurements of cross sections for the reaction 1 H(e,e′ K + ) Y, for both the Λ and ∑ 0 hyperon states, at an invariant mass of W= 1.84 GeV and four-momentum transfers 0.5<Q 2 <2 (GeV/c) 2 . Data were taken for three values of virtual photon polarization ε, allowing the decomposition of the cross sections into longitudinal and transverse components. The Λ data are a revised analysis of prior work, whereas the ∑ 0 results have not been previously reported.
