The Thomas Jefferson National Accelerator Facility has an extensive program of studying the electromagnetic production of strange particles. One of the main components of this program has been the study of both photo- and electropro- duction of K+ + â º0 and K+ + Å 0 final states. Experiments are being, or have been conducted in all three of Jefferson Lab s experimental halls measuring a wide range of observables at kinematics from threshold up to W H 3.0 GeV and Q2 from 0.4 up to 5 (GeV/c)2. The largest effort in this endeavor is taking place in Hall B using the CEBAF Large Acceptance Spectrometer (CLAS). Data have been taken at about ten different polarized electron beam energies and are currently being analyzed. Preliminary results [1] for one beam energy exist wherein the unpolarized cross section has been separated into three components: AT + eLAL, ATT , and ALT . The data indicate a t-channel dominance for the â º0 production and a strong s-channel dominance for Å 0 produc
