The ratio of longitudinal to transverse structure functions, σL/σT, has been extracted from recent beam-recoil transferred polarization data for the p(e,e′K+)Λ reaction. Results have been obtained for W=1.72, 1.84, and 1.98 GeV at an average Q2 of 0.77, 0.69, and 0.61 GeV2, respectively. Our results indicate a ratio that is systematically slightly smaller than previously published results using a Rosenbluth separation.
